Most Favorite Thriller Show?

Hey guys,

This is my first post, and/or question, what is your most-favorite thriller show? My all-time favorite is Sherlock. Tell me.

Thanks.

Promised Neverland is very good if you don't mind anime

"Sinester" is an Apple Tv+ original series. It is incredible; I do recommend watching it without looking up much about it; makes the experience 10 times better
