I am a huge supporter of creative freedom in all aspects, and that also includes being allowed to do cliches. I know you are not trying to say people shouldn't be allowed to do them, and granted I do get tired of a few myself. The arrogant bad boy with a rough past so he has an excuse to be a jerk, the "smart" character that beats an honorable character because he's devious and lucky (but people claim its because he is intelligent), etc. But at the end of the day, it's how you use them. That's the difference between Tropes and Cliches. Sauron could be a pure evil being and that is boring to some people, but he could also be a corrupted Maiar spirit who was tainted and driven crazy by Morgoth in the War of wrath and wishes to emulate his Ainur Valar master in the 3rd age. It depends! Stereotypes can be fun if you put interesting twists into them as well (bar actual racism). A stereotypical "girly girl" or a stereotypical "foreign laborer" can make sense in universe and even be valued as heroic and important to the plot, moral center, or climax of a story! The girly girl in Dragonball, Bulma, is also a brilliant scientist and without her a lot of things would have gone to hell, even if she can't fight. An immigrant laborer can (and probably is) also trying to do best for his family because he loves them, and moved to make a better life for them. It's annoying when people use cliches and stereotypes just to use them, without any fluff. But they can be fun if you do them right!
