A ringing and overdue defense of Michael Cera that makes one very important point: A more hyperactive actor in the title role would have made Scott Pilgrim unbearable. (Greencine/photo by K.C. Armstrong)
The real question is whether he realizes that he's playing a very specific new mold, a post-90s line-straddler trying hard to be non-offensive but still interesting. Many people find that kind of self-consciousness/-paralysis intensely cloying and solipsistic, but that's calibrated into Cera's performances: he always has to learn to be a little more communicative and self-assertive by the end of the movie, even if it's uneasy to tell by his surface mannerisms.
