i was interested in death note and attack on titans, thanks for the quick explanation1) Stein's Gate - jumping between timelines, hadron collider, rewritten future, etc. Long acceleration, but very interesting.
2) Code Geass - the power of the eyes makes it possible to give an order to any person once. The uprising against the empire in the face of one man, fur, is a very twisted and interesting plot.
3) Attack of the Titans - a pseudo apocalypse associated with giants who devour people during the beginning of the era of gunpowder. An interesting story, a lot of battles, blood and meat. The main character can turn into a titan.
4) Death note - a notebook in which they write the name of a person and the cause of death, and he dies ... No more hoax, everything happens in our time in the style of a hard detective. Very interesting.
5) Diary of the future - a game where each participant receives his cause of death on the phone, one must survive. The two main characters are a simple sissy and a psycho stalker in love with him. Stalkerism, blood, meat in our time is practically without any hoax except for the future SMS themselves.
I've been watching anime for over 10 years, and it seems I've reviewed everything that fits my favorite genres. And these five are the best of relatively short anime. I mean without Naruto, Bleach, etc.
