I've only seen Avatar so far. I'll be seeing Sherlock on Wednesday (and I expect it to suck, so hoping to be surprised).
I want to see the other two, but not sure I'll get the chance at the cinema, so they may have to wait for DVD. 7.5/10 for Avatar. Apart from the story being rather obvious, there's really not a lot else wrong with it.
11/4 Robin Trower
3/5 Maiden United
7/5 One Machine
