J.M. Barrie first created the character Tinker Bell to appear in a play (Peter Pan) and then in a novel (Peter and Wendy) but her worldwide popularity is no doubt largely the result of her appearance in the Disney film that first appeared in 1953, Peter Pan. Tinker Bell later became the official Disney "mascot" in versions of the television series variously known as Walt Disney Presents, Walt Disney's Wonderful World of Color, The Wonderful World of Disney, and The Magical World of Disney. The point is, she has been a major entertainment figure for more than 50 years and, at one point, was so popular that she received more fan mail than all others, including Marilyn Monroe.
Of course, children could not care less about her history but they continue to be delighted by her charm and energy. Tinker Bell is by nature a creature whose greatest talent is to "tinker" with whatever needs to be repaired; rather than pots and pans, she uses fairy dust that enables children to fly. Children love to explore secret places as when following Alice down a rabbit hole, or Peter Pan and the Darling children through an open bedroom window and then high above London at night, sailing with Geppetto, Figaro, and Cleo into Monstro's stomach, or visiting Pixie Hollow where Tinker Bell and the other fairies live. As in countless other Disney features, the production values in this film are outstanding, the music is seamlessly integrated with the plot developments, and the humor is appropriately playful. Also, I think the running time (78 minutes) is just right for younger children.
No need to list the special features. Others have listed them and they do add substantial value, although the younger grandchildren with whom I see them seem interested only in the games whereas I much prefer the background material. Some animated features (including the Disney classics as well as several produced by DreamWorks and Pixar) have an almost unlimited shelf-life, retaining great appeal throughout and among various age groups. I doubt if that will be true of Tinker Bell or, for that matter, Peter Pan. However, that said, I think that those who have seen it, as they grow older, will still enjoy seeing it again and again with younger companions if only to observe their delight. For me, the fairy dust has lost none of its potency after all these years...and never will. How wonderful!
