I didn't like Saw IV. I know I'm late but I wasn't around for a few.
Saw I - my favorite film of all time
Saw II - cheesy, hilarious that the girl from 7th heaven is in it
Saw III - really inventive movie structure, but such a grossout
Saw IV - confused the first time, watched it again, realized it's because two of the actors could be twins
Saw V - fell asleep in the theater
