I'm calling this recommended, but perhaps I'll qualify that as only recommended for paintball enthusiasts (No, really!). Now, I'm not just saying that because of the paintball element, but because this is the crazy never-happen scenario that every 13 year old paintballer has played in out in his head while cleaning out his barrel at the end of the day: "What if something REAL happened, and all we had were these paintball guns?" And funnily enough, it's exactly what you expect would happen: paint balls do not equal bullets.
This movie quickly devolved into a chase/survival film, of sorts, and was actually mildly entertaining. The premise and setting is borrowed from the much creepier Hostel, which is interesting, and JUST unique enough to tip this one up from the 'not recommended' group.
Movie to Skip: The Chronicles of Narnia: The Voyage of the Dawn Treader
This movie just feels really long. What's worse, cousin Eustace is even more annoying in person than he was in the books (just shy of Jar-Jar Binks level annoyance for ruining every scene he's in). All that having been said, it is still a great story that is very faithful to the original C.S. Lewis story. And there is enough eye candy to carry this next movie in the series. If you liked the first one, you'll probably be ok with this one too, but it isn't quite as good. If it weren't for problems in continuity, I'd probably just recommend just skipping this one.
