Even though "Geek Charming" borrows heavily from earlier teen movies, such as "Can't buy me love", "Clueless" and the like, the execution is fairly neat.
The storyline is a typical rom-com about a geek and a popular girl where the romantic plot and the transformations of the lead characters through their interactions are perfectly predictable. Where this movie is different is that it shows more clearly than any other teen move I've seen (and I've seen plenty) is that the whole popularity issue is a by-product of the American obsession with celebrities. Granted, being famous brings a ton of perks and revenue streams from TV commercials, but that is only for the show. Personal life is something else. The trouble with high-school kids is that they sometimes so much aspire to a celebrity status that they end up convincing themselves that such status can be obtained by simply winning fake admiration of a subset of their peers at school. This movie shows that becoming a high-school celebrity is an objective hardly worth pursuing when stacked up against the alternatives such as friendship, love and developing one's real interests.
The acting is decent and the lead characters are very likable.
In sum, it might not become one of the teen movie classics, but for those who like the genre, it is definitely worth watching.
