Chris Weitz did a much better job of directing this sequel, in my opinion. On the whole, it definitely followed the book a little more and kept more of what I consider to be essential story bits.
The makeup was a little strained in some places but loads better in others, and the glitter turned out more noticeable this time.
Kristen Stewart put slightly more life into her character this time around, which is a relief, as Bella bored me in Twilight. She and Rob claim to have this awesome chemistry but you really didn't pick up on it until now.
The wolf pack was great, but totally deserve more screen time. Whatever animatronic or CG they used for the wolves was almost completely believable.
