the war chief is not the master. he was created before the master existed and timewyrm exodus (written by dicks!!) tells his whole backstory and origins on gallifrey, which crashes with the idea that hes the master. its not anybodys place other than the original writers to make this decision, and especially not in this weird way where it's implied but not confirmed. that bit rlly pisses me off. other than that, its great! the colourisation is perfect, all the colours pop but in a way that you forget it was b&w in the first place, and for a ~250 min story cut down to ab 90 mins, the editing was well done, the pacing felt good. some amazing model work is there as well, with the exterior of the war dome, the tardos and sidrat models, and cool cgi. the only problem might be the sound mixing, the new soundtrack is wonderful but its too loud and so the dialogue is hard to hear. not perfect by any means but i do love these colourisations and would like to see more in the future. tomb of the cybermen pleaase!!
