I definitely agree that 3D is nothing more than a useless gimmick at this stage. Avatar utilised 3D greatly to its benefit for what its worth, turning an otherwise shitty Dances With Wolves/Pocahontas/Ferngully chimera into an enjoyable spectacle... but at the end of the day, nobody really managed to capitalise on its success with anything quality*. If the market continues to be oversaturated with shitty "3Dsploitation" attempts, it'll be like fifties 3D all over again - no-one will give a fuck anymore and it will GTFO back to obscurity. Also, I don't know if the same thing is happening in America, but a lot of the cinemas near me in Scotland are either doing away with 2D screenings altogether or moving them to smaller screens - resulting in them always being sold out and completely rammed, because more people choose to watch in 2D than the cinema expects.
I really hope that 3D cinema will succeed though, because it could be better for the entertainment industry in general once they learn how to utilise it properly. First things first, someone needs to figure out how to improve the shitty glasses, which is my major deterrent against watching anything in 3D. Then the filmmakers from the art cinema world need to stop decrying it as "the death of cinema", pull their fingers out and actually make some creative and innovative stuff, to help lend a little legitimacy to the form.... Do for 3D what La Nouvelle Vague did for film editing, or what German Expressionism did for film narrative, or something. Point is: if 3D cinema (and the 3DTV, Nintendo 3DS etc) fails to catch on as the new standard, I'm gonna have to wait longer until someone feels its necessary to invent neat, immersive sci-fi shit such as VR/AR/cyberspace/the metaverse/the matrix to supercede 3D.
*- Jackass 3D is about the only exception that comes to mind. Other films Toy Story 3D and Alice in Wonderland 3D may have had some critical and/or commercial success, but I doubt they were better or more successful because they were in 3D. That's a pretty large leap in logic, there.
