Unrealistic

Rating: 3/10 (13 February 2020)

A bald, psychotic "teacher" verbally, emotionally, and physically abuses drummers, sometimes to the point of suicide. It's almost hard to watch. The main character is a masochist who crosses paths with the teacher and it's a match made in heaven.
They don't explain why other than the drummer, all the band players are mute, or why the "teacher" doesn't abuse them too.
Very hard to buy someone getting hit by a giant truck and walking away. Are they hinting at super powers?
