When Fukuda makes a comedy/parody of a Japanese high school brawler, I take notice. The thing is that the genre isn't very serious to begin with, so if you want to do a proper comedy it really needs to be extra. Fukuda is one of the few people who can actually pull that off, but here he dropped the ball a little.
Maybe it's because the film is part of a franchise, which may have limited Fukuda's potential, but From Today, It's My Turn offers little more than a basic story about a proper student who ends up in the wrong school and has to fend for himself while gangs fight it out around him.
Compare it to the Cromartie High film, or the more recent High & Low franchise, and this one simply falls short. The characters aren't crazy enough, the plot is just average and the gags are rather predictable. That's not to say there isn't some fun to be had with this one, it's just that Fukuda can do better, especially when handling this type of material.
