A recent conversation in a discord group reminded me of something important. If you're on the younger side (under 25 or 30) and you haven't seen all the incredible, dark and disturbing fantasy films that came out in the 1980s and late 1970s, then I would strongly encourage you to do so. There was something so dark about that genre during that time that I absolutely adore and that isn't really around in modern films for children and young adults (once they learned that it traumatized a whole generation of us).
My faves in case you need any recommendations. (Some of these are really not appropriate for children, so keep that in mind lol).
The Dark Crystal - 1982 - the Skeksis will give you nightmares. I am honestly very proud of the remake for being just as disturbing if not more so than the original.
Watership Down - 1978- NOT FOR CHILDREN - Jesus Christ why did so many of our parents show us this film at a formative age? It's all about trauma and death and displacement and there's literal blood and murder. Not a G Rated Film. Still, it's very good. Loads better than that CGI remake from a decade ago.
The Secret Of NIMH - 1982 - Incredible movie. Minor disturbing elements. Probably my favorite on the list. It's just a great adventure story with real world issues (animal experimentation, mental health problems, disabilities) and there's even a lovely romance. Highly recommend.
Legend - 1985- This film is just straight up disturbing. Yes, there's a lot of beautiful shots of unicorns and sexy, 20-something year old (insane Scientology wack job) Tom Cruise and gorgeous Mia Sara, but there's also torture, madness and literally the Devil (Tim Curry is the entire reason you should watch this film)
Labyrinth - 1986 - I only really have two words. David. Bowie. My 10 year old self found out about a lot of burgeoning kinks while watching that man prance around in eyeliner and a codpiece. It's a wonderful adventure as well - if you ignore the blatant romantic and sexual tension between Bowie and an underage Jennifer Connelly (none of us could)
The NeverEnding Story - 1984 - Lots of disturbing imagery in this one! The Nothing was fucking terrifying, and the creatures in this world seemed uniformly creepy, but still incredibly well done. Love the adventure of it.
The Princess Bride - 1987 - Not technically a kids film maybe? Lots of adult themes and adult jokes, but safe for kids imo. I adored it and still do. Incredible performances by Cary Elwes and Mandy Patinkin. R.O.U.S, Hello! My name is Inigo Montoya! (need I say more?)
The Last Unicorn - 1982 - A beautiful film with stunning representations of innocence, good and evil. Just gorgeous really. I should rewatch it as it's been 20 years or so.
