If you like mature and dark animes like Parasyte, I would suggest Monster. Like Parasyte, it is a great horror and seinen anime. It is a little different than parasyte as it is not about supernatural beings but about a serial killer. Monster is also by Madhouse Studios (the same studio that is making Parasyte).

Murder! Violence! and Mystery. Both anime contains main character trying to cope with the changing society and trying to resolve the matter on its own hand. Both features, similar setting and deals with the nature of murder and mystery.

Although there are many differences, they are both great if you enjoy series with good quality and dark undertone.
Both anime explore the same question - What separates human from monster?
Monster does this via a character drama exploring the monster within all of us, as its protagonist chases what he see as the biggest monster of all.
While Kiseijuu does this via showing the contrasting differences and hypocritical opinions between humans and the alien parasite, as its central pair continue to grow closer together from a mental state of position.
