Kat Dennings is literally perfect in this movie.
I cannot believe how young she was back then and still packs her famous enormous breasts. The parts where she wears the spaghetti strap shirt exposes them so well especially. But even her casual outfits could not contain these. Her lips are almost as big as her breasts, when comparing her face relative to her chest, and they way they are so juicy red in this movie, those kissing scenes were so immersive, with the audible kissing I felt easily self inserted.
She has such a wide range of emotions in this movie. She comes off as so friendly and accepting to Charlie while every one else did not. She also becomes sad and angered with her father and I was convinced, it hurt to see a beautiful girl like her cry. And then to top it all off... her singing. Such an angelic voice to harmonize with the guitar melody. She keeps on impressing, this girl an do anything.
For her, I'd rate this movie 10/10.
