This is a VERY hot topic with me and friends (and we have all seen the movie anywhere from 5-10 times each between the group of us).
Edward (Rob)- was AMAZING! Firstly, I think he pulled of the Chicago accent splendidly. Secondly, he really portrayed the "tortured soul" bit that Edward embodies. He made me believe that he was Edward. Not to mention that he looked the part
Bella (Kristen)- was alright. While her plainness and awkwardness definitely screamed Bella, I had trouble finding the real emotion that Bella makes so obvious through her narration. Plus it was EXTREMELY difficult to focus when she would bite her lip and shake her head so much. I understand that she is trying to portray Bella's shyness and whatnot but honestly...it looked like a seizure..or tourettes at times. (Don't get me wrong, i still love Kristen Stewart and overall think that she did a good job!!)
Carlisle (Peter)- Apart from being heinously white and blond (HA!) he was spectacular.He was every bit the father figure that I imagined while reading. The unspoken moments between him and Edward were perfect and explained more than any dialogue could have.
Alice (Ashley)- Alice was perfect and I am SO glad. I had my doubts at first (the whole model turned actress thing always leaves me skeptical) but she was fantastic. I kept forgetting that Alice didn't play a very large role in Twilight and was sad when I didn't see enough of her.
Emmett (Kellan)- Oh my god. So I don't think there has been a more perfect casting since time began. Emmett was the source of the majority of the laughs for me (Besides Eric..who was HILARIOUS) He played Emmett as if he WAS Emmett. Perfecto.
Rosalie (Nikki)- Rosalie was also played perfectly. The perfect, snobby, blonde, bi-yatch. I hated her. Not the actress or the acting, just Rosalie. In which case, Nikki Reed did her job well, because I've hated Rosalie since day 1. Yay!!
Jasper (Jackson)- Oh he looked so pained!! I loved Jasper, especially when you got to see him looking more than constipated (baseball anyone?) Jackson really does hit Jasper head on. He was great.
Esme- (Elizabeth) Another person that I wanted to see more of. But what I saw, I liked. Especially when Carlisle bites her...oooooh very nice.
Charlie (Billy) He did an EXCELLENT job. Is it wrong though that I have a micro-crush on Charlie? What can I say, the 'stache is a little bit sexy.
Jacob (Taylor) Besides the bad wig, he was great. He really is a very talented actor, especially for being so young. I can't wait to see more of him in the next movie!
James (Cam) In the brief half hour or so that we saw him, he was great. I was every bit as terrified of him while watching the movie as I was while reading the book.
Victoria (Rachelle) OH JEEZ! This is just the tip of the iceberg for her. was anybody else terrified as she came down the stairs right before credits? She is amazing and I can't wait to see her resurface!
Laurent (Edi)- I love the character or Lauren and Edi played him perfectly. The whole "Let's not play with our food" thing was delivered just how I imagined Laurent would say it. Yay Edi!
Billy Black (Gil) He was great. A good actor
and when he gave Edward the "evil eye" as they drove by each other...well, I know it was supposed to be menacing but I couldn't help but laugh.
Angela (Christian) She was great. I loved her just as much in the movie as I loved her in the book.
Jessica (Anna)- She did a good job making me realize how much I dislike Jessica. Meaning that she did very well!
Mike (Michael) Oh Mike, you poor,poor Bella-rejected boy. He was the perfect Mike and really funny at that.
Eric (Justin) HOLY CRAP he was so funny! He might be one of my favorite people in the movie...no joke.
Tyler (Gregory) Tyler was also great. the "school friends" were great. They pulled off the whole mundane school thing to play a perfect contrast to the amazingness that is Bella and Edward.
Whew. Sorry that was so long winded.
