A remedial maths class tries to get out of studying over the summer vacation by offering to take lunch to the brass band (who are playing at a school baseball game). The girls manage to hospitalise the entire band (with the lunch) and are then forced to replace them. When the band recovers, some of the girls still want to play and decide to start a rival jazz group. The plot is very formulaic, with a few sub-plots and side-stories to fill out the running time. Basically, the hopeless girls must come together to beat the odds and take on the other bands in a competition at the end of the movie.
While the story is very simple and there are few surprises, there are some good jokes spread throughout and genuinely amusing situations. The main problem I had with the movie was with the writing, as some of the dialogue seemed forced and the girls’ speech sounds unnatural. The second problem is that the leads are not presented sympathetically from the beginning and you have to do a lot of work to figure out why you should be rooting for them. A few of the jokes do fall flat for these reasons, and others are so predictable that they provoke little laughter. That said there are a lot of positives; the direction is good and the girls jazz performances are fantastic.
The film works as a feel-good comedy, albeit overly similar to other films in the genre, such as “Waterboys” (by the same director) or “Oppai Volleyball”. A celebration of hard-work and enthusiasm, and the power of music to inspire a lazy, ill-disciplined generation. Probably one of the better examples of the genre, but it occasionally feels almost too cynically put together, lacking a real emotional core.
