I really enjoyed this! Especially after Space Babies irritated me; this feels like a return to form for openers personally.

The premise is incredibly funny, and I love how it was executed! Gatwa and Sethu are amazing, and I looooove Belinda already! Give me conflict! Give me a companion who doesn't take The Doctor's BS, and calls them out on their gross manipulations! And yes, good give me The Doctor's gross manipulations and address them - something 11's era didn't do enough for me with how he treated Clara.

I loved how this episode looked too; especially the robots and how many trippy sequences we had. The time explosion is literally what I want regenerations to look like again, ala Classic Who.

The twist was VERY silly in all the right ways, and it's great how unsubtle its commentary is. I don't care about subtext if I'm having a good time, which I am! Get those incels OUT OF HERE!!

This all being said.... With how fast paced it all was, it was hard for me to feel emotionally invested in the Sasha 55 plot, despite RTD's repeated attempts to make me. I knew her for all of 2 minutes! Why should I act as if she's emotionally important to me, just because The Doctor cried and everyone told us she ruled??? Tbh this ties into my biggest criticism of the episode: none of the side characters really mattered or got to be characters due to the pace. Also Manny was a little much, huh? At least he's very buff..... 

All in all though I really enjoyed and thought the tone balancing was great (again, unlike Space Babies), so I can't wait for the rest of the series!
