The movie that comes to mind for me is Matango. It’s a 1963 Japanese horror film by Ishirô Honda (the director of the Godzilla movies) that IMDb describes as “Shipwrecked survivors slowly transform into mushrooms.”.
I was curious what other PG horror movies people like. I find a lot of the time the limitations or target of an age rating can become noticeable and distracting.
Matango is a great shout.
I’d add the following (although I am in the UK so can’t guarantee these 100%):
I’ve enjoyed the Hell out if all of those, partly because it drags in a lot of Horror Comedy.
Man I remember seeing Paperhouse as a little kid on tv late one night spending the summer with my grandmother.
That shit was intense.
Although if I remember correctly there was a scene that was rather inappropriate that really had no need to be there (or filmed).
