Which Genre tropes can't you stand.
My personal two are:
1) Falls are never fatal. Whenever a character falls of a cliff they never die. This goes doubly so for protagonist who often find some lost martial arts or master. Its got to the point where whenever this happens I just stop worrying for the character's survival.
2) This martial arts should never be taught but there is always a manual. There is always some forbidden art that is considered so evil that individuals or entire schools go to ridiculous lengths to keep it hidden, yet for some reason they always keep a manual.
