Have to agree with Radical Moderate. I saw Avatar in 3D and it was cool, but it didn't do anything for me other than go "Hey! Neat!". Since then, the number of 3D movies I've seen has been zero. I avoid them because it was cool once and definitely didn't strike me as being worth the extra ticket money for the whole family. Going to the movies is already expensive enough and I don't think your car analogy works here either. A car with a bunch of added safety features and creature comforts is worth more money to me to protect myself and my family. I will also get 5+ (hopefully) years of use out of it. Comparably, a movie with a bunch of superfluous and sometimes annoying bells and whistles that costs a lot more to see in a theater means I'll be seeing it in my home theater (if at all) when it hits the rental shelf or cable.

That's hilariously accurate in my opinion.
