Mostly the logic. My wife showed me a few episodes because she really likes it.
At one point in the episode, all hope was lost but suddenly without any explanation the Dr explains something that makes literally zero sense. This then happens in all three episodes she showed me.
Dr Who could be good. It has promising moments. Its just a series of random events with a nonsensical ending.
The Angels were kind of a cool concept though.
Edit: At the end of it when I said it didn’t make sense, she started telling me about how it ties into some episode from the 50s or something and that episode has information that makes this episode make sense. That doesn’t work. YOU NEED CONTEXT.
