I'm so ticked off that they're making and marketing these kids movies in 3-D, but they don't make kid's 3-D glasses! We took my 4 year old son to "HTTYD" in 3-D, and he really enjoyed the movie, but he did have to hold the glasses on his face. He wound up taking them off a lot during the movie. I asked him if it was blurry (it was when I removed mine), but he said it was fine. If they don't come out with kid-sized 3D glasses soon, we won't be taking him to any more 3D versions of movies. I will say, from my point of view -the 3-D in this movie was AWESOME! The dragon flying scenes and the skimming the ocean were like being on a roller coaster!
I see one person found small glasses at their theater, but I asked and there were none at our theater. I've talked to several people who can't find them at theaters here in Atlanta either.
