Of course, most movies aren't filmed with 3D in mind and it is crappily added in post. Those suck.
3D is an enabling technology. It will not prevent bad films from being made, anymore than Ruby will prevent bad developers from creating a mess.
I don't have a problem with the idea of 3D, per se, but its implementation has made watching films in a theatre very frustrating and uncomfortable.
'Sony Pictures Imageworks designed the visual effects sequences.[54] Burton felt 3D was appropriate to the story's environment.[11] Burton and Zanuck chose to film with conventional cameras, and convert the footage into 3D during post-production; Zanuck explained 3D cameras were too expensive and "clumsy" to use, and they felt that there was no difference between converted footage and those shot in the format.[55] James Cameron, who released his 3D film Avatar in December 2009, criticized the choice, stating, "It doesn't make any sense to shoot in 2-D and convert to 3-D".[56]'
