I was still four when I first saw this movie. It was brilliant to me then, and it's still brilliant to me now. Babe is absolutely adorable, and the whole movie is sweet and lovely. It taught me respect and love (and I'd be lying if I said it never influenced me turning vegetarian).
There's violence, yes, and some insulting language, but really, it's nothing compared to what's around nowadays. Some characters died, and it made me cry then, and makes me cry now. Maa's death is rather frightening, and so is the attack on her in general. Farmer Hogget pointing a gun at Babe has always disturbed me a bit, but, hey, I was always a rather sensitive kid.
The only thing that you should really be careful about that part where Rex attacks Fly. Rex is the male sheepdog, and Fly the female one. It didn't bother me then, but now to me, it seems a bit like an abusive relationship. While it's certainly nothing that should just be dismissed, it's still something to be careful about. But, hey, at least Rex redeems himself in the end.
But it's still one of my absolute favorite movies. So sweet!
