First thing, the film is a European film with English subtitles. Nowhere on the ad, the packaging or anything states this, which I think it should.
The plot is very basic. Karate kid with Muslim family angst. It tries to be too clever for itself and explores the issue of sexism in this culture and how the young girl overcomes it to train and eventually fight. It becomes tiresome very very quickly.
The fight scenes are actually quite good, and save this film from zero star hell, but are not good enough to keep you awake from one boring scene to the next.
At a few quid, some of you may enjoy it for a couple of hours and then never bother with it again, but I wish I hadn't bothered at all.
