Flux capacitor

Doctor Who series 13. It has returned. I watched episode 1. It has a Halloween theme. Starting off in Liverpool. You meet Dan, a new companion. He is a trades man and volunteers at the food bank. I wasn't sure about the opening scene with Yaz and The Doctor or with some special effects. There is an alien that resembles a dog. You have a powerful alien that is possibly the season antagonist and I knew that he would escape. The Sontarons and Weeping Angels are back. There is a lot going on. Trying to make sense of it. New music. The Flux is similar to the Antimatter Wave. An apocalypse is taking place. The screen wasn't so clear thanks to the iplayer site.
