I can tolerate dubs in anime if they're good, if they suck, I'll watch the subs.
In live action film, I'd rather have the subs, I know they can distract from the images and the action. But I find it even more distracting when people talk out of sync.
Except in stuff like old kung fu and giant monster movies, then the cheesy dubs become part of the appeal. But when it's done for a dramatic film, it just dosen't work.
