Actually, this is super-weird.
This feeling of 3D "coming out" of the screen is caused by a thing called "negative parallax", and things receding into the screen caused by "positive parallax".
Avatar actually had a comparatively mild amount of negative parallax, compared against things like Jim Carrey's A Christmas Carol, which was LOADED with it.
Negative parallax can look really bad and cheap very easily. It takes a light touch to make it look good. Avatar did it really well and used it sparingly, so that when it DID happen, it surprised you - the "duck and cover" moment. Other, shitty movies use it everywhere, to the point where you no longer notice it - the maximum negative parallax becomes your 0-base (subjectively).
