I. Hate. Boxing. Storylines.
If a show runs for long enough, it's inevitable: you will get a boxing / fight club storyline. It's typically used to represent the repressed rage of a male character, but, my god, is it so boring. Riverdale, Weeds, Shameless... every time I fall for a show, it's inevitable that they're going to introduce an arc that involves fighting.
I hate it so much. Add poker storylines to the mix too. It just feels so uncreative, and zzzzz.
