No, I didn't see the 1st Atlantis movie(Mainly because I heard it wasn't a major success) but I'm sure it was much better than this pathetic excuse for a movie. This "sequel" was just plain awful, the story was boring, and I definitely noticed something weird about Milo's voice. Every time he spoke, I was so confused on whether he was being voiced by either Scott Weinger(voice of Aladdin) or Jason Marsden(who voiced Max in "A Goofy Movie" and Kovu in "The Lion King 2"), it was just kinda annoying. Not to mention I had no idea Milo was originally voiced by Michael J. Fox, who I think is quirky as the voice of Stuart Little. I also had no clue that Disney linked 3 different planned episode stories together, and they had the nerve to call it a movie. The stories in this "film" are really boring, and out of any Disney direct-to-video sequel, this one has the 2nd worst animation(behind "Hunchback of Notre Dame 2"), and just as with every Disney production like this one, It will never recapture the magic and beautiful animation of the original theatrical film. 1/10.
