Following an underwhelming past two months which have consistently demonstrated that interest in 3D movies may not be as high as theater owners and movie studios would like, the 3D version of Warner Bros.' adaptation of DC Comic's "Green Lantern" debuted to an anemic 36% attendance rate.
3D is not failing just because nobody watched the Green Latern movie. The Green Latern movie failed miserabely because it is a very crap movie. It sucks more than the biggest black hole in the universe..
3D is failing as well, becaus it is implemented very very horrible and people don't want to cough up another thousand dollars when they just were lured into buying an HD TV.
Personally i'd rather have a monitor/tv system with lots of different inputs to connect all the crap that needs a tv. I mean, 5 x HDMI, 2 x RGB, 2 x VGA, 2 x DVI-D, 4 x SCART, etc. etc.
