I much prefer Angels Take Manhattan because it's not as slow and I love the time period. It's one of the few episodes I can go back and watch when I feel up to it.
I'm not sure what was so bad about the recent appearance of them in The Pilot. Apart from the fact they had the same accuracy on the main characters as a stormtrooper, they killed all the other ground troops and had to go against a being was was pretty much invincible. In this instance I feel it's justified, but you are certainly correct on all the other occasions. They are basically the Third Reich, but acting like a Nazi is only one half of the equation here.
But yeah, I'm not that happy with his run bar a few gems. Clara has to be one of the worst companions ever because she had this super toxic 'strong woman' personality that goes far above even River. It became a parody and you just wanted to put a metaphorical pillow over her smug face to shut her up. He just couldn't kill her off either, so now she is apparently flying around annoying everyone and creating conflicts or something. I won't get started on the Matt Smith era writing for Capaldi, which totally fits obviously. /s
Anyway, this material is basically an interpretation of the universe like the LoO that Tech is discussing. I think that is why some have had a hard time not inserting the LoO into the fiction bracket. There's a lot ideas floating around about the universe and our existence, so one ideology is no more important than any other in my opinion. I'd actually have loved Tech to have explained everything in bullet points to begin with, then it would have made comparisons (with current science and fiction) much more interesting to me. I mean, the topic became like a Christian discussing Christianity with nine Muslims whom know nothing of Christianity. It's not going to work very well and the other group will become disinterested and talk about 'Allah Who'. I think you are a bad teacher Tech, and now you are giving up on us because you expect us to read something that isn't very well structured (you even admitted it was hard to grasp). It's a miracle it's lasted this long to be honest.
