I don't know if you and I have the same taste, but here's some of my favourites:

TV series: The Dragon Prince, Lucifer (adult themes), Glitch (adult themes), Wolfblood and Watership Down. All on Netflix.

Movies: Alien Movies, The Conjuring Series, anything that's spooky. (I'm a bit of a horror/thriller nerd)

Books (this is going to be a long list sorry): The Dragonian Series (adult themes but SO good), Maximum Ride, Foxcraft, Spirit Animals, Wolves of the Beyond, Wings of Fire, Throne of Glass (adult themes), Inheritance Cycle, Nevermoor Series, Troubletwisters, Fire with Fire, Watership Down, The Most Boring Book in the World (Brian Falkner, also published as 'The Project'), Chronicles of Ixia, Loki Where Mischief Lies, The Girl King, Wicked Fox (Kat Cho) and Gone Series. There are so many more that I honestly cannot recall right now, but I honestly recommend checking out the books/series above. I've added the authors to books that might be harder to find. :)
