Sky Blue is actually an interesting movie, probably worth to see, actually I never seen it but seem like a nice movie.
Bubble Gum Crisis is a old school anime but don't blame it to be old since there is a lot of them that are really good.
I would recommend these they really made me think...
-Welcome to the N.H.K.
-the whole .hack series
-Higurashi no naku koro ni
I thought all of them were really Great hope it helps
if you want to watch new anime then i would recommend gilgamesh, it's got some scientific stuff going on but is clearly explained in the subtitle. if you want funny anime then i do recommend genshiken. it tackles issues that otakus are familiar with plus it's funny and only a few episodes long
I know a pretty good anime called lucy lied.
It actually has a little nudity but not like in between the legs or anything.
The storyline is really good though but theres a lot of blood and cussing.
Crest of the stars
Banner of the stars 1, 2 and 3(just came out, only 3 episodes i think)
Desert punk (funny show, ummbad language and adult humor if you dont mind that)
Golden boy (classic show, only 6 episodes long but i almost guarantee you will find it funny.)
Try something different, like Honey & Clover or Beck. Little violence, if at all, but those should make for great viewing if "artsy and sensible" is what you mean by "mature".
If you work for a living, why do you kill yourself working?
