I like Midnight! Not liking David Tennant or the tenth Doctor much, I like it when he's put on the back foot or even sidelined (see also Human Nature/The Family of Blood and Blink). I was also glad to see the programme attempt something different after a season that felt very tired and repetitive to me.

I agree it can be hard to watch, though, and like The Massacre it is probably a story easier to admire than to watch for fun in the way one would watch, say, City of Death.
