I really didn't like it. I actually thought it was dreadful. I'm sorry, I really really tried to enjoy it! Idgi, I loved Twilight even though it's cheesy as hell, I thought New Moon was lovely if a tad slow paced, but this was just awful. The wigs/hair were awful (I weep for Rob's head), accents were awful (what nationality is PFach trying to sound like?), acting from the twifecta was awful, the score was awful, the editing was awful, the dialogue was REALLY awful.
I did like: the title screen (lol), CGI wolves, Rosalie and Jasper's flashbacks, the training scene, LEAH and Riley. I'd say I enjoyed maybe 9% of the movie.
ETA The worst thing about it is the COMPLETE LACK OF MICHAEL SHEEN. I know he's not in the book but still.
