How old is your nephew? My DD got too scared from an action scene at the very beginning of a 3D movie (the character jumped out at/from the screen) that she wouldn't wear them all through the movie! She's only 2 though so she didn't mind the blurriness...You can still watch the movie without 3D - they always have it in both 2D and 3D (although 2D will probably be a smaller screen).
