I remember really liking this one on my first watch, and yeah, it is just a comfortable watch for me. It's packed with action from the start and the mystery of the planet kept me intrigued. The TARDIS being the "Ghost Monument" is actually such a cool idea and the race is pretty compelling. I'm liking Jodie's Doctor much more than the first time too, she is actually pretty badass when it comes to calling out people for what she believes is wrong (except for the no guns speech, that was a bit ham-fisted imo). The writing is nothing crazy but the vibes more than make up for it.
