There were definitely a few that I intentionally left out in order to get the post out on time. I may revisit them in the future.
Call b.s. on me if I'm incorrect, but The Simpsons Movie was done by Gracie and distributed by Fox, no? I'm pretty sure that's why I didn't cover it. I elected to not go over Teacher's Pet and Recess: School's Out, which were distributed by Disney, for the same reason. I heard TMNT was awesome-looking, but the plot non-existent. I have it on our DVD shelf, waiting to be viewed at a later date. But, yes, those are more examples of characterization and story being the foundation on which a film of that length must be built.
I enjoyed some of the 2D films too, but I can admit that they were definitely flawed during a time they needed to be stronger.
Quick example. I adore Fox's Anastasia. I thought the conversations between Anya and Dmitri were fairly authentic couple dialogue. I'll say that Once Upon a December, with its haunting melody, is bar none my favorite song from an animated film. The rest of the songs are entirely forgettable, which could be detrimental to an animated musical. Also, the heroine and villain have absolutely zero interaction until the end of the movie. Rasputin might as well have not been in it at all. Sadly, as I stated above, it was also very much derivative of what Disney was putting out at the time and they didn't do it any better.
