I'm currently enjoying a lot of Nelvana cartoons, they're my second-favorite Western animation studio ever.
I just saw Rock & Rule for the first time, the first full-length Canadian animated feature ever. It was weird and different, and very interesting. Especially if you're into Lou Reeds, Debbie Harry, Cheap Trick, or the other big-name bands they got to do the music. On the same DVD was the short "The Devil and Daniel Mouse" from the 70s, which is really cute. It's based on The Devil and Daniel Webster, it's a half-hour Halloween special, and it's really well done. It's fantastically well-done if you remember just how much of a ghetto '70s American animation was. I would definitely recommend Daniel Mouse, though I think Rock & Rule is very hit-or-miss.
I also think Care Bears Movie II: A New Generation is a fun movie, and a really great lighter-and-softer Dante retelling, surprising for a kid's movie. I think there's a lot there that a lot of people just don't see because they go "ugh, Care Bears, whatever." It's not hugely deep, but it is a little more than people give it credit for.
I also like Babar, the series and the '89 movie. It was on Netflix for a while, then it wasn't, then it was, and now it isn't. I'm also a huge fan of the Sam & Max: Freelance Police franchise (comics, cartoon, games) which they handled marvelously. Like Rock & Rule, it's high-quality but a very specific taste that not everybody can get into.
Anyway, they've got a lot of great shows, and the animation is always above average. Check out their website where they have a list of all the cartoons they've done (except Care Bears) http://nelvana.com/Show
Speaking of Care Bears, there are a lot of movies I wouldn't consider good or quality, but that doesn't mean I don't think they're fantastic in their own way. I have a video discussing both Care Bears Movie II
and another favorite of mine, Felix the Cat: The Movie
(it's sort of a long one.
) I wouldn't put either of them up on a pedestal as the best, which may be missing the point of this thread, but it's definitely one of my favorites. Especially all of the political subtext they didn't mean to put in it, but which totally works.
Has anybody ever seen the Danish animated film Samson & Sally, about a pod of whales in the Arctic? That one was really good. It's kind of exceedingly dark, with a number of on-screen and implied deaths, but it's got a good moral even beyond the obvious "save the whales" agenda. Something about not depending on your heroes to come and save you, you've got to be your own hero and save yourself. It was my childhood favorite, and I think it holds up very well.
And as long as I've gone listing my favorite cartoons, the post would be exponentially longer if I talked about how much I loved Disney cartoons and movies. I'm a Disney nut and have been for twelve years. I'm moving to Florida in a few years to have a career in the theme park offices.
