It's sort of disheartening, in this supposedly sexually liberated, feminist age, that we're still so slavishly willing to roll with that hoary old horror trope of equating sexual promiscuity with horrific dismemberment, but apparently we are -- you pretty much know right when the two girls take their shirts off that they will later be eaten. But let's skip over the prelude of hedonism right to exactly 45 seconds in, when a scary hollow noise lets us know that our carefree weekend is about to get shat all over by something scary, because that's when the shit gets truly ridiculous.
First of all, did the fucking black guy seriously just die first? Yes he did, so we can conclude that this flick will either be stiflingly self-aware or lack any self-awareness whatsoever (I'm guessing the latter). Also, how is there a shark in a lake? Oh, because it's a... um... salt-water lake, you know? And how did the sharks get into the lake. What if somebody put them there? OMG!
Okay, that makes sense, because it's some kind of sick game. To what end? I don't really know, but I'm probably going to take a pass on finding out.
