I.. I knew how many LBT movies they have, but I don't accept any after the first one[footnote]and the Fievel series ended at 2.[/footnote]. It was beautiful, perfect in it's own right from start to finish with no need for anything else. It was, for the most part, a perfect movie. Emotional, non-pandering, and had scenes that to this day hold up gloriously. Giving it a sequel would be like making a sequel to Wizards, unless you truly respected the tone and feel you was always going to pale against the original.
The sequels took what was a rather mature story and turned it into just a regular direct-to-dvd fluff that can be put in so that the kids can watch the pretty colors and shut up for an hour. No more compelling then a Carebears movie..
