It’s excellent until it isn’t. Yeah, Boom Town is kinda the perfect example how much the finale of an Episode matters. The Dinner Scene with the Doctor and Badland (I forgot the name of her Character) is easily the Highlight of the Episode and tells us so much about the morality of the Doctor, which is very important, especially for the new viewers. Bringing back one of the Slitheen and actually make it work (sorry Aliens of London is a confused mess) is wonderful, shame there was never another attempt of doing one. Dont really care for the Rose and Mickey Drama in this Episode, it’s not bad and actually really well-written and performed, but ehh never clicked with them. I do think RTD writes Domestic stuff in Who superb but that never gets me for some reason. But the finale… I am not sure, it feels kinda like a tonal clash, yes this Episode had goofy moments but the solution is a bit too much for my liking.
Overall pretty enjoyable
