I agree with White Chicks (although I thought it was a pretty positively received movie?
shocking that it's rated so poorly on RT)
I feel like The Butterfly Effect doesn't get enough praise... that movie was amazing. Chappie is pretty poorly viewed as far as I know but I liked it (a lot).
And something from the horror genre too, Wrong Turn is one of my favorites (I even kinda like some of the ones they made after the original).
