Take it from me. The best-limited series are #whodunit stories because the point of a limited series is to solve a problem in one season, usually 6-10 episodes. #Whodunit is an easy enough problem to solve over a set amount of episodes. Consider it writing a movie over 10 hours instead of 1.5. Just don't forget that EACH episode must have its own goal/problem to solve that leads to the overall answer.
