A coming-of-age film based on the 1999 novel of the same name, “The Perks of Being a Wallflower” is not your typical U.S. high-school movie. Charlie (Logan Lerman) starts out as the archetypal freshman loner, but when he meets Patrick (Ezra Miller) and Sam (Emma Watson) he begins to find himself. Avoiding genre cliches, director and author Stephen Chbosky employs a great alternative indie soundtrack and touches on serious issues ranging from love and friendship to suicide and sexual abuse. Watson gives a mature performance suggesting her post-Harry Potter career will be a bright one. 102 minutes.
