I watch every movie I can in 3d on my Epson projector (5025UB), and I've got a huge collection. Animated films work the best because everything is in focus front to back, and in general they're brighter. Plus they can do fun stuff to take advantage of 3d. Still, I love watching the Marvel films in 3D. My family tires of 3d but not me. Keep it coming!

Like other have mentioned, the best place to get new 3d movies is amazon uk. If you buy multiple movies, it's cheaper than the advertised price because you get a shipping discount. Pay in GBP with a cc that doesn't charge a foreign transaction fee. If you pay in USD, they charge a 3% premium over the current exchange rate (but they don't tell you that).

Ratatouille in 3D is Region B. So for that I have to use a computer with PowerDVD Ultra and set it to Region B.
I also have some 3D movies from Russia, like Kung Fu Panda (1), Wonder Woman and the Shrek series. eBay for those. Can't read any of it but they have the original English audio tracks, and are region free.
