Tenshi no Tamago

Both rely on aesthetics and atmosphere to tell most of its story and it's philosophical message. They both share dark undertones and a somewhat bleak (black-grey) colour gradient and can only be appreciated and enjoyed if you try your best to understand them.

Both have similar shoujo style character drama and yuri undertones. (Moreso Utena) And both tell a story with 2 female leads, who are different like night and day and characteristically rub off on each other.

Kara no Kyoukai Movie 1: Fukan Fuukei
|
There are similarities based on how the mystery element is portrayed and they are both quite dark series. Although Kara No Kyoukai has a bit more of a mature tone and theme, both series are great psychological/mystery anime's, and they will both mess with your mind.
