If you want to talk about abnormal killing, you must watch Hannibal series and The Silence of the Lambs, but personally, I think other movies such as Dark Attack series, Silent Hill, Wax Museum of Horror, Death Comes, Moonlight Panic, Seven Dead Cities and so on. It's also very good, and the scariest thing is the horror wax museum.

Some soap operas should be in line with your Dexter Forensic Medicine, which is a bit bloody, and the paranormal phenomenon is a bit scary occasionally.

Only introduce what you have seen.
