Actually, the acting wasn't entirely as bad as many on here are portraying. The lead actor and the woman who played his wife actually did alright. The big problem with this movie - other than the glaring historical accuracies, like; why was it docked in a Boston harbour during WWII when they were fighting in the Pacific theatre against the Japanese? Why would the torpedoes still be armed? How could the batteries still be charged? etc., - the problem was the script. And I don't even mean the military aspects of it either. It was laughingly atrocious, full of cheesy lines, juvenile at best. It seemed to steal lines from every bad war movie ever made, like the line where the guards at the gate to the Naval base roll their eyes and say "civilians", or when they quote the 'there's only two kinds of ships" saying, that can be found on any submarine gift-shop t-shirt. If the script had been better, this movie may have had a chance to rise above it's almost unwatchable level.

Did not enjoy it ,probably down to bad acting Not much I can really add Obliged to write 10 lines at least Was looking forward to a good story line ,, ,disapointment Actual filming was quality Jack Daniels well advertised, , me personally it gives me a stinking hangover Heard the F word plenty of times Was impressed by the actors white teeth , was impressed by some of the locations, Im glad I never actually paid money to watch it, I would have been demanding it back I cant believe I have to write so many lines for it to be submitted, ,, , absolutely hate waffling on , feel so sorry for the people that have to read all of this,looking back the actual movie was professionally made, looked good but just so amazed at the totally bad acting

Well, I saw this movie and thought, hey, Not too bad. Reading some of the previous reviews I thought this movie was going to suck. But it didn't. as a matter of fact I had several Coworkers come to my house and watch and they agreed it was a pretty kewl movie. Now Clearly as a Sci fi action movie it's going to have a few things that might not be completely explainable so one would have to use ones imagination because it's a SCI FI MOVIE! I was impressed with the fact that it was a REAL WWII Submarine. I've been in one, it's a tight squeeze! And these people shot a full length movie in one. I like authenticity in the era of WWII and as far as uniforms, equipment goes it was pretty darn good. Yes there was a scene or two with some modern items in it but most of the stuff you saw was original to WWII. I have not seen that in many modern WWII type movies. U571 was close to authentic as was Below but here it was spot on. I felt the acting was pretty good for these new comers. C'mon, you ever see Costner's 1st film??? Very BAD acting. But he improved.Listen Bottom line, for a SCI FI Action Movie, it was pretty good! YES a thumbs up! Sci fi fans will like this movie, WWII History fans will like the stuff they see in the movie. It's worth the watch.Better than most Movies you would see on the Sci fi Channel.

the way it ends makes no sense and they don't even try to offer up an explanation since there is possible way that a sub stuck in 1943 and on the bottom with no batteries in 200ft of water could possibly magically end up back in 2014 and above water where some guy opens their hatch and climbs down into the sub and then gives back a tablet computer which still powers up after 40 years when my tablet won't power up after three years on same battery. He then claims that the info on this tablet allowed them to win WW2 which as I remember we already won when we dropped the bomb in japan twice... and the laptop had no mention of atomic bomb or physics or whatever. I mean most time travel movies stretch the suspension of disbelief but they all follow simple time travel do's and don't which this movie's writer apparently never took note of... and the characters in this movie were all never developed or even established at all, not to mention the poor dialog which as I already mentioned could have been written by a 10 year old for a one night homework assignment to be generously rewarded with a C- if the teacher was in a generous mood or perhaps an illiterate. I gave this movie 1 star because I couldn't give it a half star or a quarter star which is what it deserves. Don't waste your time with this movie unless you need lessons on how not to write a screenplay or what not to do when making a movie about time travel. It doesn't even deserve this lengthy write-up which is far more entertaining than the movie itself if I do say so myself.
