Hmmm. Overall, cliches don't bother me much. If I don't like something, then I don't read, watch, consume it. Easy as that.
If I had one to pick: it would be:
TRYING TO MAKE FANTASY STORIES REALISTIC.
See for me...Fantasies are escapism, and why would I want to make that escape the exact same as my own world? I wouldn't.
Honestly I don't like these kinds of threads, where everyone bags on creators that are just doing what they like. It's gatekeeping at its finest.
Hey creators? Make what you want to make, if you want to change the status quo, then do it. If you want to make cliche stuff, go for it. Create what you want.
