Directors who've spanned the full range of good/bad movies.

Ah, see, I haven’t seen Ocean’s 12. And apparently I should keep it off the rent list, too.

And The Island of Dr. Moreau.

Hell, most successful directors fall into this category; aside from Kurosawa (even he had his off-films, but nothing really bad) I can’t think of a single director who didn’t crank out some bit of crap during his career. Heck, even Cameron has to answer for Pirana II.

Paul Verhoven

Tim Burton–yes, even Mars Attacks (one of the most fun movies I’ve ever seen)!John Waters was in this category until “Cecil B. Demented”.

You’d be wrong.

Much as I love the fat old man, even Hitchcock had a clunker or two. Did you ever try to watch “Spellbound”? (the Salvador Dali dreamscape was the only watchable element in that entire flick.)
I’d like to nominate Gus Van Sant

the good: My Own Private Idaho, To Die For, Good Will Hunting, Elephant
the bad: Even Cowgirls Get The Blues, Psycho
