From a purely positive influence? Anything on PBS (wasn't allowed to have cable growing up)
- Sesame Street
- Mr Roger's
- Any documentary with David Attenborough
- same with Jane Goodall
- Nova
Bill Nye would be the one non-PBS show I remember having an impact
Modernish stuff? Bluey, Miss Rachel, Pixar especially Wall-E, Brave, Coco, Soul, Encanto, Toy Story, Inside Out (when a little older). I like Coco, but Book of Life is an underrated alternative too.
