The first film in the Twilight Saga truly proved that a bad director can destroy what is meant to be a good film. New Moon was ok - but that was mainly because of Taylor Lautner being all big and... tanned. Eclipse, however, is actually a good film.
Bella no longer makes me want to scream at the screen because of her excruciatingly bland character - she actually smiles in this one guys. Edward is pretty good. He isn't so, how shall we say, scrawny in Eclipse and cracks a jokes once or twice too. Jacob is divine - Taylor Lautner couldn't be more perfect for the part. The only annoying part is that Bella choses Edward over him (what is wrong with you?!).
As well as the miraculous transformation off Kristen Stewart (she also looks beautiful throughout the whole film, and is how Bella should be), the story - in my opinion - is the best out of the whole series, as we get to see Rosalie, Jasper and the wolves' stories, and there's constant vampire an werewolf action, oooo yah.
I don't know if you can tell, but I'm definitely and Emily, not a Bella.
I just hope Bill Condon doesn't ruin breaking dawn, which to be honest has the potential to be a complete disaster - the story is a little far fetched, Stephanie Mayer.
