Love the story line, humor and acting, but the fight scenes are unrealistically brutal finishing up the final episode of Season 1, and continuing on into the following 2 seasons. Who walks away from multiple kicks to the head, torso punches and throws into walls and into glass without serious, if not fatal injuries? And for the most part, these are kids beating each other up.
The unnecessary violence, and fight scenes that go on far too long, undermine the appeal of the strong character driven story.
