I've never seen any active 3D, only passive at the cinema but I certainly don't have any problem physically with that format.
I agree that it's a mixed bag. When done well (not too common) then it definitely adds something to the experience. I can still remember watching Avatar at the cinema & there were many times when I simply could not believe what I was seeing. I thought you needed to take LSD to get an experience like that.
I'm sure it's also stunning to look at in 2D so my observations aren't fully objective but the 3D showing blew me away.
I can imagine maybe 1% of films at home might be in 3D but if it doesn't compromise 2D performance then I can't see why I wouldn't buy a 3D PJ.
If anything, the extra requirements of 3D (extra brightness) seems to be improving 2D performance so it's win win!
