5. Open Water 2: Adrift (2006)
http://www.youtube.com/watch?v=SItuuvHmZdk It's A Sequel To...Open Water (2003) For the most part, the original Open Water movie - despite being produced on an incredibly low-budget - made for a pretty horrifying watching experience. If Jaws put you off going swimming, then this is the movie that will put you off of, uh, going on holiday with friends. If you've seen Open Water, you're probably wondering how the hell you'd make a sequel, given that - shocker - the main characters are murdered horribly by sharks. But as we've all learned, what use is a movie title if you can't exploit its success to sell another, completely unrelated movie? That's where Open Water 2: Adrift comes in, a sequel that completely disregards the existence of the original flick (which makes perfect sense, given that Open Water 2 is based on a script that was written before Open Water). The plot is, genuinely, about "a group of douchebags stuck on a boat."
