Out of the ones listed I'll have to go with The Dark Knight, but my personal favourite is still Batman: Mask of the Phantasm, which was one of the earliest movies I went to see in the theaters. I found my DVD copy a little while ago and re-watched it and I'm proud to say that it still holds up as a great movie for kids, and an even better one for adults who now have an understanding and context for all the adult things going on in the movie (alcohol, sex, bachelor living, etc.) that the movie had present but never felt the need to dwell on. If you haven't seen it, you will definitely want to search it out, it's well worth your time and money.
