As long as you don't go into this expecting too much you shouldn't be disappointed. Yes, it's a stock-standard, generic, clichéd B-grade slasher flick. The cast is pretty unlikeable which makes it hard to even care who lives or dies. The "teenagers" all look in their mid to late 20's (expect for Isla Fisher, who really is a very talented Aussie actress, but maybe I'm biased).
A lot of the characters have obscure accents which can make it a little hard to understand what the hell they are saying at times. The killer does kinda look like the killer/s out of "Scream" but I guess they're starting to run out of costume ideas. The machete was a strange weapon of choice, not exactly easy to conceal.
Oh look, I could go on and on about this movie's flaws but instead I'll just say this: if you're looking for half-naked chicks, horny, drunk guys and a few brutal, bloody murders then look no further!
I will commend the person who thought up the water slide scene though. It should be inducted into "The Most Original Way to Die in a Movie" hall of fame. As a female all I can say is "That's GOTTA hurt!!!".
The pool complex itself is beautiful, modern and luxurious but we don't even get to see it until about 40 minutes into the movie. Wish the pool I worked at was half as groovy! 6/10 for effort. At least they tried...
