There's a thread already on what fictional cliches annoy you. So i thought it might be a good idea to get a thread going about the fictional cliches that you like.
Personally, I am a fan of the flawed hero cliche. I love anything where the protagonist is either somewhat morally flawed or has a grey side.
I must say I also love "good" winning in the end. People can die, even the protagonist(s), but so long as in the end "good" prevails over "evil", I like it.
