The newest Tinkerbell movie is really good (they all are!). I think it is called Secret of the Wings.
The newest Diary of a Wimpy Kid movie just came out...not sure if it is appropriate for preschoolers, though.
I can't think of any new movies that are appropriate other than those. I don't see any new ones coming out soon, either.
Hotel Transylvania is coming out at the end of this month. I haven't seen it yet so I don't know if it is okay for preschoolers or not. Same with Frankenweenie. I agree with definitely not letting them watch ParaNorman, though!
