Joss Whedon.
Whislt I won't deny his talent at fixing scripts which he is pretty good at and he can write a decent female character.
I just find him uninspired and heavy handed ( I mean firefly is a western set in space literally) and his pop culture references can be extremely tiring and overwrought, and I hate that its never his fault for anything for example he blames Jean-Pierre Jeunet for Alien Resurrections failings.
