^ This. So much this. Don’t watch this if you’re claustrophobic or can’t stand the sight of lots of blood.
SPOILER – The movie he talks about is Watership Down. If you’ve never seen it, well… it is literally an hour and a half of pure childhood trauma. I too remember being shocked by the G or U rating. They had this in the library at my school… kids could check it out whenever they wanted. I can only assume that the reason it got away with that rating was the prevalent attitude toward animation at that time – that anything animated was just for kids. But really this movie is PG at the very least – never let a child watch it unless you’re very sure you and they can cope with the nightmares they will have for years afterwards.
