Don't you think Kristen Stewart act better in New Moon that in Twilight?

I think, for the trailer I have seen, Kristen act better :D in this movie she puts more emotion to every scene... :P
in twilight she only had one face, so to speak... but in New Moon... she has improved somewhat, and that's good xD
I know that this movie has more action and conflict but in the first film too, and she just has the same espreccion in most of the scenes... but I liked it so... what do you think guys??? I'm wrong???
