This movie is a great example of missed opportunity in nearly every scene, a flat attempt at parody that only hit just often enough to keep reminding you of what a better movie it could have been with a good script, better acting, and competent direction. Everything it tried to do has been done so much better already.The opening scenes invoke a zany little Office Space or The IT Crowd workplace with unique characters, and then within ten minutes throws all of that away to pigeonhole them into a cliché script ripped straight out of nerdy 80's high school wish fulfillment fantasies, before they even leave for the jungle. Van Damme never even gets any good lines and barely features in the movie (though a couple of scenes near the end were silly), the two main men could barely act their way out of a wet bag, and the women are just set pieces to fall for the men. Completely uninspired camera work means that the lush, verdant locale was all but thrown away, to boot. That just made the scenes that were hilarious stand out that that much starker, and those few lines are all that earn it one extra star.It obviously set out to parody the milquetoast-to-hero genre, except it forgot the plot and turned into just another bad example of the genre, instead. In no way does it stack up to actual send-ups, like Blades of Glory, Napoleon Dynamite, or Office Space, let alone full on parodies like The FP and Talladega Nights. Go see one of them instead.

However, it was not JCVD's fault. He was OK. But as others have mentioned, the writing - both the lines and the plot could have been way better...At times it feels like it was written by someone who wanted to make a funny movie but has no comedic sense, so they tried to force the funny.I think the best humor comes from actual actors ( but not these), especially when they play with the material/do different takes. Instead, here they just say dumb things. I disliked the wimpy lead/too nice cliché..,he ends up playing it very unlikeable. Jason Biggs in American Pie was wimpy and awkward, but funny and you want to root for him! But again, that's writing.About the casting...I think most (85%) of the cast was bad. I like JCVD, Dennis from All State...the funny- allison hanigan like girl, and the Asian guy...but everyone else- that is, another 6-9 character sucked. And JCVS's Son -I don't like him...I've seen him in a few of his dad's films now.Ir just seemed cliché, poorly written, and not believable. The leads friend has disgusting man boobs-like meatloaf in Fight Club. told ..and I felt like the director told him to act like Seth Rogen...I gave it a 3 out of 10. It looked good, locations wise, camera wise...all it needed was more interesting costars and better writing.JCVD says "i was tripping balls" it made me cringe because, I donor believe he'd ever say that...

This movie is strictly for people who enjoyed Office Space, Dumb & Dumber, Dodgeball, Ace Ventura, etc. and have the capacity to get over themselves. It's absolutely ridiculous, immature, and goofy like all of those other low brow comedies but with a way smaller budget and considerably less starpower. It's not a thinking mans movie and will never considered for an Oscar but I think anybody with common sense realizes that 5 minutes in. It's definitely not an instant classic either but people on this site are being way to hard considering what this is. All the acting is more than adequate for a screwball comedy and it has it's share of laughs and silliness. I'd recommend it for the people who just want be amused and entertained for a few hours by a little of absurdity.

The movie maker might have thought using Van Damme would brighten up this movie but terribly failed. It is not funny, it is not adventurous and it is not even look like a big screen movie. The quality of production was the only interesting thought they did not spend it wisely and broadly. You can watch this movie from first to last, but you can't enjoy it any portion of it. This movie was based on a silly concept with okayish actors in it which looked like a weekend movie that aired on a television. Hope you guys won't end in a disappointment like me for choosing this movie to watch.✰✰✰✰/10
