[ClannadDango]

I've distance myself from anime because I thought the stories were boring but once I saw Clannad I changed my opinion and started getting into the anime/manga/visual novel medium.

I wanted to know if there were any anime/manga/visual novels with complex, groundbreaking, or good storylines like:
Clannad
Kanon
Cross Channel
Ever 17
Saya no Uta
Umineko
Higurashi
Death Note
Paranoia Agent

I guess stories like Twilight Zone, X Files, Matrix, Inception and stuff that have complex storylines and are metaphysical but no so much as they are confusing and don't make sense. Stories that are still grounded in the real (modern) world.

Thanks
