I like themes that are mysterious, intellectually stimulating or straight up weird but I'm not into a lot of really long combat scenes or drawn out romantic intrests. My favourites have been Serial Experiments Lain, Paranoia Agent and Death Note. (You can rec movies too but I've seen all the basic Miyazakis, Takahatas, Hosodas, Kons and Yuasas) Doesen't necessarily have to be heavily dark themed, dystopic or tech-based I also like just absurd strange humor like in The Ping Pong Club.
