I just finished watching Angel’s Egg, an OVA by Mamoru Oshii made in 1985. That is pretty anime, lots of well drawn scenes, with interesting character designs and nice atmosphere. I’ll post a few pictures so you can see some of what I mean.
The anime is simple and silent, with barely a few lines of dialogue here and there. But you can watch it if you want to see how good you are at reading symbols. The anime more or less tells a story with them.
I am sure you will be able to figure out what the egg stands for and what the end of its and the girl’s storylines mean. Also try to see what the fishes stand for, that is a bit more interesting. And all the dead fossils too. And if you figure out what the angel is all about, then do tell me, that one I am interested in.
