I haven't watched "Dark Water" in several years, and I had forgotten how much I love it! I remembered the twists, so the foreshadowing had me cackling. I love the Cybermen eyes on the doors and when their theme music starts to play as our protagonists figure it out. I love Missy! She's probably one of the most fun characters to watch on-screen. Also, I always love it when Osgood showed up. She and Missy are now some of my favorite characters.
