Welcome to WatchMojo, and today we’re counting down our picks for the top 20 TV plot twists of the century so far. For this list, we’ll be looking at the best story turns that were revealed on the small screen between 2000-21. We’ll be sticking to one plot twist per television show. Foreign language and animated series will be excluded here because they could each have a list of their own. And while it probably won’t surprise you to hear this, there will be major spoilers ahead.
