I thought it was okay. I do hope the Gorn are gone for good though. They just can't do anything interesting with them given where they have to end up, unless they're willing to just retcon and shoehorn in something different. Like some B5 thing where Batel has to go to the Gorn planet because she has some Gorn DNA in her and is the only one that can try to talk to them ala Sinclair.
I did think it was funny that suddenly Mitchell was a character for a fleeting moment. It felt like her name was said more in this episode than the last two seasons, but I could just be forgetting. It's weird that she's there most of the time, but she's not a main character... it's the Discovery problem, although obviously not as bad.
