I dont know how much of a cliche it is by itself, but here's some of my biggest peeve:
Saturation:
Several of the examples mentioned above fit this. Kill characters too often, revive them too often, repeat patterns of any kind and I'll become desensitised. Modern superhero comics are obviously the worst offender her. Whenever someone dies in dc/marvel it has zero emotional impact on me. I feel more like "ugh, wonder how long befor they come back".
Everyone falls in love:
When groups of characters, typically with an equal male female ratio, all have to ducking fall in love with someone of the opposite gender. Is this the only way to portray relationships. Honestly, I'm so happy whenever I come across a story that doesn't revolve around a romantic situation at all because of this. There has to be more options to characters relationships than this.
Grimdark:
Talking about oversaturation again. I have a big problem with (especially main) characters who are meant to be "dark and kewl" and overdo this. I think it's absolutely possible to make a character with these traits but they can't be the only traits they have. But I want them to have more to them than just being quiet, grim, dark and violent. On an aside, when a character rarely speaks or gives you insight into their persona it feels to me like a writer is playing it safe or isn't really sure who their character is.
All the above said, I'll throw in my vote with "any cliche or trope" can be done well. Cliches doesn't mean a story is bad. I'll certainly have some in my comic. It's almost impossible to expand on every little thing so some aspects will appear more cliche than others. But give me an interesting spin on a trope and I'll be there to comb through your story.
