I need help to make a good anime list for language learners.

If you watched anime to improve your Japanese, which ones did you find the most useful and why?<br><br>I'm looking for shows that meet these three criteria:<br><br>1. Dialogue is spoken at a relatively slow speed, possibly because it's a children's anime, or the dialogue is very short.<br>2. The vocabulary is relatively basic.<br>3. The accent is neutral.<br><br>The shows can be TV shows or movies, but must have been professionally produced.<br><br>I need these to support a project that I've been working on for a number of years, and I don't want to recommend any shows that are poor quality or not useful for learners.<br><br>Any suggestions you may have would be appreciated.
