They movie tried too hard...
to be funny. I think they were aiming for classic along the lines of "Friday". But failed miserably. The first time I saw the movie, I thought Em's character was odd and could've have been left out. Or perhaps if he had proper introduction. I watched it again, Em, still feels out of place. I think they were trying to make him humorous/derange, but he just seems deranged.
Liked the random cameos, that's about it.
