PG movies for 3, almost 4, year old kids?

Idk how I feel about this. I wanna preserve their innocence but my husband is pushing to play PG movies for them. I feel like it’s because he gets bored watching the age-appropriate, G-rated movies and shows such as Daniel Tiger, Magic School Bus, and Mister Rogers Neighborhood. But I’m like why do we need to rush this? Just let them be kids and not expose them to language/behaviors they don’t need to be exposed to yet... Agree? Disagree? If you agree what’s a good way to convince him of this
