Avatar in 3d was awesome. Easily the best 3D ever.
Since then, the movie industry had attempted to disguise lack of plot & poor filmography by making the film 3d, and then charging a premium for it.
In a world with internet and imdb/rotten tomatoes, consumers are better educated, and we aren't falling for their usual advertising waffle that's crammed down our throats by media saturation.
The movies industry needs to lift their game, rather than blamestorming.
