Next, you'll be complaining that movie theatres should do more to cater to blind people.
Some cinemas do have (optional) audio description in some screens.
A lot of the initial movies with new features over-emphasized those new features, rather than telling a story. I expect nothing less from 3D. I'd also be unsurprised if, in 20 years, people raised their eyebrows if someone said they were only releasing a movie in 2D, just like you would now if someone released a movie in black-and-white.
I would expect 2D films to continue to be produced. Whilst some films benefit from 3D, most do not. Also customers will refuse to pay the surcharge to see a lot of films in 3D if it does not enhance their experience.
For TV, a lot of the time it is on in the background, so most viewers would not want to have to wear the glasses. Other shows, such as news programmes, will only be in 3D for the studio shots, not the field footage.
