HMM.. Okay ill give you a few options but the whole link thing. Most are on netflix

These are all different categories

1: God/Feels/Sad/Death (not religion biased): Angel beats. Found a link here. This one you have to let yourself roll through it a little bit. It's weird and highschool based, but it is definitely not what you think
2: Action/Serious/Heroic/Creepy/Death: Attack on Titan. Here's your link. Attack on Titan is pretty awesome, and the anime has not yet finished. Basically HUGE human beasts who are insanely creepy and have one goal: to eat people. People live behind a colossal wall in order to keep them out- but that won't save them. Basically taking the view of "anthill vs humans" and switching their roles.
3: Fighting/Lighthearted/Comical/Serious Themes/Heroic: Dragon ball/z. You can watch all dragon ball series here. Dragon ball shows the story of a young kid named Goku who pursues martial arts, to find himself (and a few others) surpassing human limits. Its easy to watch and feels very classic to watch. Dragon Ball Z expands upon this, Goku older and as a father and husband. This one is still comical and lighthearted but gets rather heated at time. Don't bother with Dragon Ball GT, different authors terrible plot.
4: Adventure/Mystery/Large-Cast/Expansive World/Creepy: Fullmetal Alchemist: Haven't tested this link but it is by funimation and should work. "Alchemy; the science of understanding the structure of matter, breaking it down, then reconstructing it as something else. It can even make gold from lead. But alchemy is a science, so it must follow the natural laws: To create, something of equal value must be lost. This is the principle of Equivalent Exchange. But on that night, I learned the value of some things can't be measured on a simple scale. My brother and I knew the laws of science, of Equivalent Exchange, that gain required sacrifice, that something had to be taken from us. But we thought there was nothing more we could lose, we were wrong…". This is a long anime, (although not nearly as long as dragon ball series). It's very good and has intense character development. The creepiness is probably the best i've seen implemented yet and even the hero has flaws which helps the viewer relate to. Its great, I just finished it.
