It really boils down to this: if something to me is worth it, I'll pay the money to see it. If it doesn't, I won't. I've become much less of a movie-goer in recent years, which is coincidentally the recent years that 3D has become a "thing". If enough people still want to see 3D, though, it'll continue to be a thing. If they don't, it might not. Who knows.
Capitalism--it does stuff.
Kind of sounds like everyone is just either going "YEAHHUH" or "NUHHUH" at this point. I trust Charlie to know his shit, and I respect that. I think it just boils down to the fact I just don't care about the theater experience all that much.
