For me, the argument that 24 fps is "more cinematic" is silly. Its just something we've HAD for a 100 years. That's all. It's something that we are used to. We've been trained to accept as HOW films should look.
But WHY, why does motion blue equal more cinematic?
As far as it being "to realistic," I think as the technology improves, along with the cinematography, costumes and etc, I don't think that will be a problem.
And to be honest, I would LOVE it if it felt like a stage play. Stage plays, for me, are a more intimate experience, a more immediate experience.. For me, a stage play is watching something happen right in front of me, where as a movie at 24 fps is up there on a screen. And to be blunt, I've never lost track that Ian McKellan is playing Gandalf at 24 fps. I'm along for the story, but he doesn't magically literally become Gandalf.
