Despite its average, many-times-seen-before plot line(s), I really enjoyed this movie. It reminded me of watching 80's movies most of the time, it was cute and funny. Not overly special or fantastic, but definitely time well spent. I loved Emma Stone, and while I didn't quite buy Amanda Bynes as a high school student in this (and her acting was kind of terrible compared to the others in the film), the cast was decent.
It's a movie good for some laughs, though I am not sure I would buy that any of the actors were high school students, probably because they have been seen playing college students elsewhere. I enjoyed this enough to keep it around at least long enough to watch it again down the road.
