I recommend all the Disney movies. Be prepared to do just a little "damage control;" e.g., in the movie Pocahontas, there is a strong suggestion of "pagan religion." Just be prepared to talk quietly to the children and bring them back to the solid Christian principles (e.g., say, "God created such a beautiful world, didn't He?")
A few "hidden" gems in the Disney movie list--get the movie *The Three Lives of Thomasina. * This is a beautiful story about a cat, and there is a great deal of Christianity in this movie.
Also don't miss Pete's Dragon. This is a great movie that has beautiful music and teaches strong Christian values, especially the values of patience and faith.
The Rescuers is another often-overlooked movie from Disney. Bob Newhart and Eva Gabor do such a good job of voicing the two mice leads, and Genevieve Paige is, IMO, the most frightening Disney villainess ever.
Finally, Robin Hood is amazingly accurate in regards to English history, and the score is written by the incomparable Roger Miller--very singable!
One more--The Princess and the Frog is an incredibly good movie. I don't know why this didn't get the major publicity hype that so many other Disney princess movies get. Whoever wrote this movie did a lot of research into Louisiana history and culture, and the music is fantastic.
As for non-Disney movies and shows--
My girls grew up watching Dr. Quinn, Medicine Woman, and now that they are 25 and 27, they both own the DVDs of the complete shows, and they sit and watch them whenever they get together. (They call it "DQ night.") Although the last seasons of this show were rather "liberal" with lots of the revisionist history about how white people stole the land from the Native Americans, it's still an awesome show. The first few seasons are delightful. Yes, there is the constant theme of "a woman can do things as well as a man," but I would not call this a feminist show at all because there are many excellent male characters in the show. The stories are so well-done, and the acting is good, too. I really recommend this show for families.
My girls both love The Princess Bride. I never cared for it, but they like it and so does my husband.
I still think the Star Wars franchise is good. Some Christians have a hard time with the "Force", but I think that with good parental guidance, most children will not be influenced negatively by this. Great heroic stories.
Another type of movie that both of my girls love is any of the Broadway musicals that have been made into films. My Fair Lady is especially pretty--the costumes won an Oscar. Also try Finian's Rainbow, Brigadoon, Hello Dolly, Gypsy (there are several versions, but I like the one with Rosalind Russell and Natalie Wood), and The *Phantom of the Opera * (this is fairly new and it's not as good as the Broadway show, but it's still good).
Try the new Bridge to Terabithia movie. imdb.com/title/tt0398808/ I am proud to say that my favorite actor, Robert Patrick, who plays the father in this movie, was told by Katherine Paterson (the author of the book, Bridge to Terabithia) that he did the role exactly how she envisioned it. This movie is a tear-jerker--everyone in the theater was crying during Mr. Patrick's scene with his son at the end of the movie! Spoiler--
One of the lead characters, the girl child, dies tragically. This was so shocking when the book came out that many schools banned this book. The movie does the death in good taste, but still--for some younger children and even young teens, this plot development could be very disturbing and upsetting and cause nightmares and fears. So please use your own judgement and do what's best for your children.
