I contend he is, but maybe there's someone i'm forgetting about who makes terrible movies as well. Bonus points for anyone who wants to go for all time worst.

No that would be Uwe Boll.
He sucks so bad that he finally ended up quitting film making.
M Night Shyamalan and Michael Bay are a close second.

I would say yes. Every film of his that I have seen is awful.1
