I don't get sick, but here are my findings:
Jaws 3D - I'm not sure what the deal was, but it didn't look 3D at all. It was on HBO maybe 30+ years ago. I got my red/blue glasses out of a Captain Crunch box, I believe. At least it didn't hurt my eyes, though, and I loved the movie.
Captain EO - perfect 3D projection, no eyestrain whatsoever. Used some sort of passively filtered glasses. The best 3D I've seen to date and this was around 1990 or 1991.
Spy Kids 3D - Horrible, horrible, horrible!! I couldn't perceive any 3D whatsoever, only blurriness or just objects moving close to the camera; the movie was atrocious, and we had to wear those old school red-blue glasses. My eyes hurt, head hurt, (from trying to get myself to perceive any 3D) and afterwards, I was seeing red out of one eye, blue out of the other for an hour or so. I probably should have let my wife drive home in case I forgot which position the red and green traffic lights were in, b/c everything had a red or blue hue to it. I'm still upset with the kids for suckering us into paying to see that steaming pile of a movie.
Madagascar 3 in 3D - Absolutely beautiful movie, but some of the 3D parts made my eyes ache a bit. I believe it was Real3D. If you haven't seen this one (not necessarily 3D), at least watch the last 10 or 15 minutes. On Blu-Ray, that is demo worthy material.
