Yeh the OG GitS film was great but I couldn't get into all the lore/introspection SaCs went into.
Ergo I just got sick of pausing to read stuff so never finished it. Pyscho Pass season 1 was pretty great, not sure why I never watched later seasons.
Elfen Lied is good/dark/weird but the fanservice is unnecessary/out of place considering how almost slapstick gory it is imo. Kara no Kyoukai (this one in particular ) is better in every aspect imo and is tonally consistent with the subject matter.
If you like Elfen Lied and are into predictions of our future technology, Mnemosyne is probably up your alley.
The main story I recall being pretty whack and is similarly gory, but seeing the progression/integration of AR/VR into human life throughout time (each episode time skips as main characters are immortal) was fascinating/believable.
Not into the whole VR/other world trope beyond Kono Suba (which mostly satires the genre). I remember watching SAO S1E1 when it first came out and thinking 'wow what a great concept' but I'd already lost interest about 5 episodes in when it became clear it was a going down the generic shounen power fantasy route. Everything I've seen since in that space since has had a similar effect :(
