I thought as an episode taken on its own, it was disappointing. But, as an episode taken in context, so seen after the 50th which was EPIC and tying together so many loose ends, it was immaculate. So many things accomplished plausibly in one hour that I couldn't even be mad. That was really impressive, and then I felt sad about Smit dying. Though I watched all of Tennant, I didn't really like his episodes compared to Smiths who was impeccable in my opinion. Smith was my doctor and I felt a bit lonely last night. Lol
