saw 7 was a total waste of money, i spent the entire film wondering how more many "i'm pointing something at the 3d camera to justify using it" moments there would be, also, it's the first in the series that doesn't seem like a piece of one continuous movie if you marathon play them back to back.
could have been worse, but.... yeah... they shouldn't have called it saw, cheesefest-money grab would have been a better name.
and for what it's worth, 6 has the best ending of all, even not counting the reverse bear trap.
