Saw Star Trek Nemesis. You feel like if someone with half a brain had spent 15 minutes doing some script doctoring it would've actually been a really good movie. But, since we never really know why any of the characters do anything that they do, the whole thing feels pointless.
Two Towers was great - though the first 15 minutes were confusing and clumsy, but after that it was impressive. Never seen CGI/live interaction handled as well as they did with Gollum.
