Tarzan & Jane is a sequel to the first Disney film but since it was a direct-to-video release, the quality is definitely not as high. In fact, it has an extremely similar structure to most of Disney's direct-to-video films, and is pretty much three TV episodes merged together to make it feature length. There is the weak excuse of Jane thinking of doing something special for her anniversary with Tarzan, and this causes her to reminiscent about past events. We then get three effectively self-contained stories where Jane's past life affects Tarzan's. For all its worth, Jane and Tarzan are happy with their lives, but every so often, Jane does want some "civilized" activities. Naturally, when you try to have tea parties in a dangerous jungle, it is not the best idea. If you enjoy the TV series then this film is a natural extension and you'll enjoy it. Otherwise, the animation is average (not great, but not bad either) and the writing is simplistic but it does touch on some deeper themes like compromising and not forcing things onto someone you love that they don't like.
