Reply #2: I think they're virtually inescapable, but can be useful, I would recommend...

Spirited Away
My Neighbor Totoro
Kiki's Delivery Service
Etc. 'Studio Ghibli' did a lot of good stuff.

Don Bluth has many great works.
Secret of NIMH, was the first DVD we ever bought.
Thumbelina
Titan AD

Almost nothing by Disney.
Although 'Dragonslayer' is one of our family's all time favorites.
So...

Basically, quality movies with good morals, with plenty of discussion about what happened.
Why. How they made the movie, why. Etc, Etc. Anything can be fodder for the thought mill.
If you learn from it and instill values from it.

Always try and aim *just* above their heads.
This will stretch them out and they will be familiar with the concepts when they get a few years older (6-7-8) and are more able to understand the tropes and patterns of storytelling.

Hope that helps.
