When I was a kid, my grandfather would record cartoon movies from TV to VHS and when we visited I'd watch those. One of them was an adaptation of Animal Farm. Of course I was way too young to understand any deeper implications of the work, but it did leave a deep impression on me. It is not suitable viewing for young kids.

As an adult I read the book and I really enjoyed it. I join OP in recommending it. It is also not a long book, so it's not a serious time investment if you don't happen to enjoy it.
