He seems like he would have been a good lead instead of this D-Bag. It almost seems like the part was written for him and he didn't accept it, so they chose a nerdy guy that was similar yet not nearly as likable or subdued.
Well not everyone in the world loves Michael Cera and I thought he fit better because listening to Michael Cera do that whole awkward whisper talking thing again I probably would've stopped ten minutes in.
Yeah the lead isn't much to look at but I think that's the beauty of this movie that's what's compelling is that he looks like the average dorky teen that no one would cast as a lead in the movie.
Yes Michael Cera is totally type-cast, but he would have been perfect for the lead in this movie. I think they went a little too over to top with the lead they chose.
