A LOT of the TV shows are absolute garbage. Prepare yourself for that.
But their are some good kids movies.
The Toy Story's, Wall-E, Song of the Sea, Secret of Kells, Inside Out, Ratatouille, 101 Dalmatians, Spirited Away, Aladdin, Lion King, Winnie the Pooh (original), Cloudy with a chance of meatballs, Hercules, Fantasia 2000, Harry Potter etc are all good flicks IMO.
Obviously some of those you need to wait until age appropriate.
