There is a fundamental difference though between the introduction of colour and sound to film and 3D. Neither of these older advances required the audience to wear additional devices to take advantage of the technology.
I agree - For me it's not a problem at a cinema, but at home it's not something that I'd want.... Who knows in years to come Smartphones may be built into glasses and people will wear them all the time!
I think it will take a really credible film such as The Godfather to be successfully made in 3D if audiences are going to be turned around. I also think that younger generations will be more adaptable to 3D, without the influence of 30 years + of 2D viewing. (I'm starting to feel like a 3D champion now and I don't even watch them!)
