The problem is, there are like five of you, you and your four friends, who care about 3D in the way that you do. The rest of the world's majority doesn't, so studios and film makers don't either. Ok, maybe five of you in each state, plus another five in the UK. Sounds about right. Yes, I'm being facetious, but only marginally. In reality it's probably like 5% of the overall market that would care, and five percent is not enough to make it worthwhile to spend the 30-40% budget markup it would bring to do it for those who invest in these projects. Keep in mind, they don't give a damn about what you, or anybody else, likes, they care about making money and unless a much larger portion of the market wants it, enough to make it fiscally responsible, it's never going to be a technology that lasts.
And for the record, I've seen plenty of 3d films, and was never particularly impressed. Then again, it wasn't "nothing" either. But for me, and the MAJORITY of those who will spend the money that keeps these projects from becoming money pits, I would never pay more for them, never go to see them in the theater and am not hurt that they've mostly gone away, because the state of current technology makes it more of a distraction than an immersion. When the technology someday becomes more inherently immersive and loses it's ability to distract from the experience, I'm sure they'll try it again.
Plus, that aside, 3 out of 4 people in the US use some form of vision correction and it is the most widespread disability that exists. Of those who must use vision correction, 75% of them wear glasses and as mentioned 3D technology is unappealing to those people. So that basically means that AT LEAST half of the potential market for 3D, can't, and won't use it. Or even if they are willing, they are going to be a lot less enthusiastic because it's probable that the second they take off their glasses a good portion of them are instantly going to have a less than perfect experience due to simply not being able to see what they are seeing, as well as you apparently do. So, really, this whole thing is not unexpected and probably won't ever be on track for widespread acceptance until they figure out a way to do it using projected augmented reality of some kind where no funky glasses are required to see it.
So, let's say 40% of the population doesn't want it for sight reasons, and let's just say that the remaining 50% simply don't care about it. That makes for like 80% of the market saying "blow off" to it. Studios and investors aren't going to spend 30-40% more on the budget to make ~20% or less of the public happy. And that's just for movies it will actually "work" with. Many movies are just not suited for this type of thing at all, which further reduces the interest in making it "better" or keeping it around.
