Joel has good ideas and has good intentions but unfortunately is too passive and lets others walk all over him, which isn't a good quality for a director. He seems nice and is great in visual design or sets but is a terrible director. Michael Bay things too much with what's in his pants than what's in his head (That is, if he has anything in there). But none compare to M. Night ShyamalamaDINGDONG!

all of his movies after The Sixth Sense were awful.I did not like Signs or Unbreakable and Split was the worst of
the bunch

I don't know who Joel Schumacher is, so I can't judge him. But I think Michael Bay has made some bad choices like the Transformers movies. I wish they would just die out already. Then there's the Teenage mutant ninja turtles, never seen it but it looks really stupid. Then we have Armageddon but I don't hate that movie it just has some cheesy dialogue and Ben Affleck who just annoys me. M. Night has also made some bad choices as well but I don't think he is a terrible director.

Times a million.

It takes true talent to mess up Avatar the Last Airbender.

Overused of CGI, special effects, and bombs in each of his movies, without a good story at all.Don't know about other two so can't judge.

Michael Bay hasn't made even one truly non ironically good movie.

He's also responsible through his production company, for making some of the worst horror movie remakes. If it ain't broke, don't fix it

M. Night has made very well directed films. He just really lacks consistency but the potential is there.

They're all terrible, but I'll vote for Schumacher since he shockingly hasn't gotten any votes.

^ Well, with the other two directors, it's not that surprising.
