There were elements to Watchmen that I enjoyed. The graphic novel was better but overall I think Snyder did a good job, not a great job, but not bad either. I enjoyed it.
So far I don't like the direction Man of Steel is going but i'm also SICK of seeing re-hashes of the original series. Superman Returns it's Lex all over again. This one, back to Zod and his generals. I'm bored or re-tellings. Superman has some seriously tough villians he can face. I'd have prefered a Smallville movie, even with sub-par acting.
I'll give Snyder a chance, but I wont hold my breath
