The worse that I saw this year were:
-Man with the Iron Fists... I really wanted to like it, but it sucked...
-Total Recall... It was good at first but down-spiraled into one of the worst climaxes in the history of cinema...
-Underworld 4... what a POS and a shame on a somewhat entertaining franchise...
-The Devil Inside... it had potential but it was average...
-Amazing Spiderman...
... the only good things about it are the chemistry between Peter and Gwen, and the Spidey effects... everything else is pure crap...
As for somewhat disappointing:
-Prometheus, I liked it a lot but failed to deliver on a few things
-Dark Shadows, I was really expecting a return to form from Tim Burton... but this was not it... fortunately he did it with Frankenweenie
-Savages... it was just OK, not Stone's best
-Resident Evil 5... it felt rushed, and lacking... for the franchise I mean...
