I give this episode a 9.
It kind of trodded on the same ground in terms of Tendi's story, but she's a good pirate when she puts her mind to it. I just got a kick of everything DS9 this episode though, from the look of the station in Animated form, to the Wormhole (Would have been nice to go through the Wormhole) and Mike did his homework when it came to DS9 continuity. I also liked seeing Mariner and Jennifer get closer together, and they make for a cute couple. The stunning sequence was funny.
I've always said that Lower Decks scratches the 90s Trek nostalgia for me and this episode did everything I wanted it to. This was like a love letter to that era (especially DS9, which has gotten ignored in NuTrek) and I really appreciated it. Also, it was awesome to get Visitor and Shimmerman back. I would have liked to see DeBoer back, but you can't have everything I guess.
