I've seen a few movies in IMAX 3D
and while some of the movies were genuinely augmented by the effects (Hubble 3D
, Avatar, etc.), some studios just use it for "shock value" like throwing items at the audience (which has been done in theme parks for a decade and is now a bit of a cliche). So as far as the movie theater is concerned, I have no problem with it as long as they're not using it to frighten small children.
The problem is that you have to wear the glasses. This is especially annoying for those of us who already wear glasses (and have to wear those on top of the prescription ones). While i do keep the TV on at home, it is usually on in the background while I'm doing something else. In fact, it's on right now.
So I don't see this taking off until there is a good method of producing the effects without the need for the glasses. Only then will it make sense for things like the news and shows. At the moment, they are primarily aiming it toward full length films, and especially animated films.
Of course, there's apparently a 3D channel in the works here and many TVs are "3D ready", so perhaps I'm misreading the market. I wouldn't want to wear the glasses at home though.
