I took my 3 year old to see Tangled. She really enjoyed it and she actually watched the entire movie. Not much can hold my 3 year old's attention for 1 hr 40 min. I too loved the movie. This is definitely our new favorite Disney Princess movie. It's a great blend of magic and comedy with a great message. The only draw back for my 3 year old was that we could only find the movie playing in 3D and sure enough, she refused to wear the glasses. However, Disney added the 3D effect as more of an embelishment and not as a gimick as a lot of movies do, so my 3 year old could still enjoy the movie without the glasses as much of it .
I enjoyed this Harry Potter movie the most of the six that have been made so far. The young actors are really coming into their own and were just fantastic! The entire feel and pace of the movie was spot on. My only caution is that this one is definitely not for younger children. I don't plan to let my daughter see it until she's at least 12.
