There seems to be an ongoing argument about the benefits of 3D movies - does it add an immersing visual experience? Or is it one additional gadget moviegoers can do without + some people are just not suited to watch movies with goggles - gives them headache, visuals seem darker etc..?
Frankly, in my view, if a movie is good enough, no 3D experience is going to enhance it greatly. If it is a bad movie, no visual enhancement is going to safe it. I haven't come across a viewing experience where I exclaimed "wow, wait til I see this in 3D". It'll be a different story if it's 3D as in Star Wars hologram (with high resolution and colour)! That way, the value-added viewing experience is you get to see the same scene from any angle that you choose.
Anyway, I have no quarrel with cineplexes showing movies in 3D. My pet peeve is if they stop doing films in 2D and put it all in 3D. That will be the day when the masses will rise against movie-makers and distributors, for crossing the line for greed. Imagine the number of goggles people need to buy/rent. The day will probably never come, because just like Blueray, what's not acceptable to the torrent community will unlikely make it big in main stream.
