I went and saw this movie shortly after it was released in theaters. I have not read the graphic novel so I can't judge it on how true it was to the original story.
I did not enjoy this movie. Michael Cera played the part of yet another awkward teenager. Most of the time I was pretty bored and at one point contemplating taking a nap through the rest of the film.
The music was mediocre at best. Maybe it was just that the sex bob-bombs seemed to only have one overly-repetitive song that was played again and again and again. A little more variety would have been nice.
The movie wasn't completely bad. The gay room mate and the vegan superman were pretty hilarious, in my opinion, but other characters, especially the protagonist, seemed to be lacking. I guess the main reason I was bored with this movie was that I could not empathize with the protagonist at all, and therefore didn't have a decent way to relate to the story. Some of the video game references were pretty cool, but in the end, references do not make a movie worth watching.
