I thought the movie was pretty good. I loved Brian Vaughan playing Boyd as the classic bad boy and the interaction between the characters was explosive, obsessive, turbulent and unusual, which made the story more real. I loved the character of Boyd's laid-back mother and her reaction to Katie and Boyd's relationship--pretty cool despite it all, though a bit unrealistic because she handled it a bit too well. The characters of Katie's parents and Boyd's friends could have been played up more though--they were cast into the background or skipped over quickly. Additionally, Katie's reaction to Boyd's actions sometimes was too nonchalant, as if it didn't concern her in the least. What made this film great was the dynamic cast, the charismatic bad boy character that Brian Vaughan played very well and the rough, gritty photography because this film didn't need all the sugar-coating and super-smooth filming some other movies have to depend on to make it interesting. Overall, I'd give the movie three and a half out of five stars.
