When reading a short summary of ''teacher'' my first thought where, this must be like ''class of 1984'' or some real bully towards nerds + protective teacher= bloody revenge..... well it became some thing like that but not so much.
what i can say though is that the main actor does a good job on the screen, and that the plot had a good float and the score made it all pretty tense. also some of the bullying where rather maliscious and even though often used as a teenage drama topic it engaged me that much that i started talking to the screen and jolting at the takes.
its actually a good film thinks the grumpy old man, the only thing missing is the bloody revenge
