[REQUEST] What Are Some Shows That Keep You Thinking?

First time posting here!

I'm looking for shows with a mystery, where each episode you're on the edge of your seat & constantly trying to piece together the pieces of the puzzle. Realistic, fantasy - doesn't matter. Just a show that keeps offering you small pieces of a stupidly large puzzle and then at the end when you finally figure it out, it's a 'OH MY GOD??? THATS SO COOL/CRAZY' type moment. I'm down for any suggestions for the main streaming services, not just Netflix.

+ Two examples are 'Pretty Little Liars' and 'From'.
