So, I'm judging both episode here. Basically... meh. I didn't hate it, didn't love it. Lots of things to nitpick, most of which are the obvious.
Really disappointed at the aliens. Reminded me of The Visitation and how all them aliens didn't really have a name per se, they were just all the same race and everything with one goal. Why can't humans be like that. Their scheme was alright but I was not awed. The multiple Earths didn't work the way I thought was going to work, and I dunno what to say. Also, The Master nuked Gallifrey... How? I mean, sure, we didn't know how the Doctor did it when the NuWho started either, but we did get the indication that it occured during a cataclysmic, monumentous struggle of beyond epic proportions. Here, its like an afterthought. I'm not sure how I feel about this. Maybe they shoulda blasted the whole planet again? Also, as was said, curious how easily the Doctor materialized there, right? Heaven Sent negated, right there!
I guess this really says a lot. The fact that the Gallifrey stuff intrigued me more than the main story, and there's a reason for that. Jodie as the Doctor simply isn't there. She doesn't inhabit the character. She's not the Doctor. She's playing the Doctor, as if she was hired for the job (well, joke's on me, I guess). And the companions continue to underwhelm. Ryan continues to be written like a dope, and Yaz, the cop of the group, is nothing of the short. Amazingly, only Graham stands out, and I give kudos to Walsh for holding my attention. His bits with the shoe were my favorites of the two-parter.
Sacha Dhawan is OK. Which means, he's probably the weakest Master yet. At least Simm got to shine in his personal moments with Tennant, and later with Capaldi and Gomez. At least Beevers got to expand (and how!) his version as the creepiest, scariest of them all (and my personal fave). At least Ainley got to be good. So, on that note, I'm hoping Dhawan can get to strike a happy balance as otherwise, given this two-parter, he's all over the place. I like his scenes with the Doctor in the Eiffell Tower, but not in 1834, where they SHOULD have adressed his change of hearts, even peripherally. I get the "casual fan shouldn't feel disoriented" but, come on. Its series 12, in a 55 year old program. Its not like them talking about the Autons from 1971 (which you the Moff would actually probbaly do, just to do it). I like the idea he's inbetween Simm and Gomez, but it seems highly unlikely.
Anyway, I can't muster any more interest for this. I'll see the rest of the series, of course. But I am about to stop hoping for improvements. The show's in trouble, in my eyes, and it likely won't change this season. Ah, well.
