As you said, 3D rarely works for you in any case around it. Perhaps you can't easily see depth perception on a screen? You don't sound like the kind of person that would think 3D = pop ups. So perhaps that has something to do with it. That would also possibly have something to do here. The 24 fr looked like a lot of other 3D films that I have already seen in the masses, it looked no better nor worse than the rest.
I have never seen this level of detail in any film. I'm someone who went in expecting to hate it, then found myself amazed by it. And while an LOTR fan, not a die-hard so there's no bias there either. I just noticed a greater amount of detail in even the more minute things that I've never seen before. As said - the smallest textures even on a rock. It was the textures of objects really that impressed me the most and showed off how much detail was there in comparison to other films.
In 'masses' I have yet to hear one negative word about it off the internet and not from film critics. Also if you include the internet, you're one of the few here Hawk who doesn't like it. It was the numerous posters here that did like that made me give it a shot. Where exactly are you getting luke warm from, except from the critics? Who, as I said, would be banned from test screenings due to their "eyes" being differently adjusted - industry reason given.
