This isn't really an episode review but more a general comment on the Thirteenth Doctor Series.

I love the casting...especially Sacha Dhawan as the Master. Although a scene stealer, his portrayal of the character is truly Masterful.  It's a pity the general writing of the series is so juvenile.  Science Fiction and Fantasy are intertwined, but the recent writing seems to be drifting away from the science and steamrolling into fantasy dominated stories. That leaves me too often disappointed and unsatisfied as I watch a great cast left in the lurch with tired, preachy writing.

Still, performances like Dhawan's keep me a fan, and make me optimistic that the writers' room will come back to life and trust the viewers to think for themsleves.
