This is a very easy question with a lot of different answers since our taste in movies are subjective. There are so many movies that would be interesting and appealing to people like you. I'm wondering if any of the following movies are familiar to you:
Any Don Bluth movie
Care Bars Movie
The Rugrats Movie
The Tigger Movie (one of my all-time favorites)
Any Disney movie
Any Thomas the Tank Engine specials (if you want to count direct-to-video releases and not just the theatrical movie from 2000)
If you know any of the above movies or anything related, then you can watch them with no problem.
