I am not sure how true it is but I read there is a positive buzz about Justin's acting in the "Social Network." Hopefully it is true and he did do well for his sake.

For the most part, both the critics and directors/producers he works with are pretty positive about his acting in general which is probably why he keeps getting roles.
But, I think there are some fans who are against him doing any acting at all because they simply want more music and that's it. So no matter how well he does in a movie, they aren't going to like it.

I understand that but, I also admire Justin for taking on the challenge of being an actor and continuing to pursue that dream even though some of his fan base isn't too happy about it.
