The low-budget Mega Shark movie franchise started before the Sharknado series, the first film was abysmal, but the following year the creators brought us another helping of the nonsense. Basically deep in the Democratic Republic of the Congo, an illegal diamond mining operation is interrupted when a giant 150 foot (46 m) prehistoric crocodile is awoken. Meanwhile in Atlantic Ocean, the giant Megalodon shark has survived the giant octopus fight, and attacks and sinks the US Navy warship USS Gibson. Lt. Terry McCormick (Jaleel White) is the only survivor of the attack, he was experimenting with a sonic shark-repellent device, while in the Congo, English hunter Nigel Putnam (Gary Stretch) has captured and tranquilised the giant crocodile. In Los Angeles, California, McCormick is interrogated by the National Oceanic and Atmospheric Administration Special Agent Hutchinson (Sarah Lieving), McCormick feels guilty that he lured the shark, he offers to help to catch it. Meanwhile the crocodile is being carried on a cargo ship, it is revealed that it is carrying the crocodile's eggs as well, without warning the shark attacks the ship, waking the crocodile, Putnam and his partner Jean (Gerald Webb) jump overboard before the ship is destroyed. Onboard aircraft carrier USS Lexington, McCormick meets Admiral Calvin (Star Trek: Voyager's Robert Picardo), he tells of the objective the hunt down and destroy the Megalodon, while Hutchinson meets Putnam, she is shocked to find out about a giant crocodile on the loose as well. They then discover the location of some crocodile eggs, Calvin assigns McCormick to accompany Hutchinson and Putnam and capture an egg, which are about to hatch, but a shark fin is spotted close to the island, an airstrike takes place. As the team leave the island, the crocodile is angered by the shark swallowing its eggs, while missiles are fired at those eggs remaining in the cave, the crocodile attacks Miami, before an arc flash fire sends the creature back into the sea. Putnam suggest opening an egg to find out the crocodile's vulnerabilities, one egg is aboard the submarine USNS Invincible, while two are being taken by Black Hawk helicopters, but the shark is attracted to them, and attacks these crafts. With no trap big enough to capture both creatures, a retrieval plan to use more crocodile eggs is devised, these are dropped in Panama Canal, both creatures are lured by them, where they battle each other, while the Navy attack, the chaos causes a tidal wave to destroy Panama Canal as both creatures continue to fight. It is revealed the crocodile has adapted itself to lay more eggs, hundreds more are laid on the American coastline, hatchlings are attacking Santa Monica pier, while the two giant creatures are heading towards Hawaii. A nuclear submarine misses with a missile attack, and is swallowed by the shark, the creature is now a bigger threat, as it has a nuclear reactor inside, while the crocodile attacks the helicopter carrying McCormick, Putnam and Hutchinson, they survive the crash, but Hutchinson is unconscious. McCormick and Putnam will use the sonic emitter as part of a new plan, to lure both creatures to an undersea volcanic range, both adult creatures are lured and fight each other, while the crocodile hatchlings come to assist their mother. Hutchinson recovers and picks up McCormick and Putnam, as the volcano explodes and detonates the nuclear reactor inside the shark, the combined blast kills both the adult and juvenile creatures, the charred shark and crocodile are still latched onto each other as their bodies sink into the volcano. Also starring Dylan Vox as CWO Butowski and Hannah Cowley as Legatt. There may be one or two faces I recognised in the cast, more than previously, but it doesn't matter, and there were more special effects to bring the giant shark and crocosaurus to life, but as before, they are awful, as is the story and the concept, another waste of time science-fiction horror. Poor!

I think the actors were the only likable factor(if any) in this movie especially Gary Stretch as the croc hunter Nigel. Hannah Cowley, who gets only few scenes early in the movie, is so pretty. If she had remained till the end, it'd have probably earned more for this movie. Yet, I felt the execution is bad enough to down any pros I can think of. Many scenes don't make sense. The mega shark and mega croc constantly tear into each other, yet a scene or two later, both show nothing on them..a downed helicopter gets back up and flies in mint condition within minutes and one wonders how the croc did that happen? and so on...The effects are also weak but that wouldn't have really mattered if they hadn't been careless about these avoidable blunders. The poor script and/or direction messed up the lot. Give it a miss.

Okay, I never thought I would say this... The sequel was better than the original! Yes, the effects are laughably silly, the acting is poor and it has no plot, but that's why you love it! This time instead of a 'Giant Octopus' we have 'Crocosaurus' (A huge crocodile) and somehow the megalodon has come back from the dead... (Don't try to figure it out.) So now we've got another super-heavyweight champion monster showdown. I watched this thing on the 'Space' channel and was cracking up at how bad it was. If I had to tell you whether to watch 'Mega Shark vs. Giant Octopus' or 'Mega Shark vs. Crocosaurus', I would tell you 'Mega Shark vs. Crocosaurus' and not have a second thought on that. If you were a fan of 'Mega Shark vs. Giant Octopus' and you have not seen this, go check it out! I can guarantee you you're gonna love it.

I would say it does not live up to Mega Shark vs Giant Octopus, but it was still good. Dr. Terry McCormick, Nigel Putnam, and agent Hutchinson were the main characters, and they did good at it. The new beast,Crocosaurus, was a good opponent for Mega Shark, especially that the fact their fight was amazing. But again they both die, this time bombed in battle {funny, nothing that big can explode under water}. The Asylum did especially good on this film, but they could of reused Emma and Lamar.If you see this movie and think its tacky at the beginning, be like me and say, "well, can anyone get a robot that big?" because animation makes a good movie! They did well to show the Crocosaurus 3 minutes in and the Mega Shark 10 minutes in. The places the characters first see the beasts are accurate The Democratic Republic of the Congo and well, no duh, the ocean. My guilt is not quite finishing this, unless I shouldn't be guilty. These movies remind me to watch the other, after this I'll finish 30,000 Leagues Under the Sea, and start Dinoshark. You should really see and review this movie. But remember, animation always makes a good movie, because who can find a huge robot to replace it, right? yes it does because it is the only Red Box movie you can find.But more about the movie. So two gigantic monsters trying to slaughter each other. Crocosaurus want to protect his eggs. Mega Shark wants to escape extinction.But what I don't get is, the film makers have a real aircraft carriers but have to animate helicopters and... TRUCKS!?!?!? Wow, but anyway we all have to love the confidence the Asylum have in themselves they can make better and better movies, but really, Nazis From The Center Of The Earth?!?!?! Wow.Wow. Wow.The visual effects are worst than usual, because they keep repeating the SAME thing!But the fight with the Crocosaurus and the Mega Shark is better than the one in Mega Shark vs Giant Octopus,because again in that movie they repeat the same fight scene.
