Personally, I don't see the major issue with regards to this current trend of 3D media. I mean, it's just the natural evolution of televisions and movies; much like color was back in the era of black-and-white. I wouldn't be at all surprised if over the next decade or so, more media will eventuall make this shift (can you imagine FPS games/video arcade games using this?). Much like color in the past, what needs to happen is for moviemakers to stop using it as a gimmick and for people to slowly adjust to this developing concept.
It's not evolution if it requires accessories to watch it, it's just a revamped version on an old movie trick. Until they invent 3D without the requirement of glasses it will always be a gimmick, especially the 3D TV nonsense that's been touted lately.
