I'm going to be harsh, and I'm sorry if I ruffle any feathers here, but I'm giving this episode my lowest grade of the season, which will be a 3
This show is stalling and I'm frustrated by that. All this character work could have been done earlier and now we are 3 episodes left before the end of the season. I appreciated getting Tarka's backstory, but we've kind of heard it already when we first met the guy. This was a 50 minute soap opera drama about feelings and the theme of making connections but I'm like "Let's get on with it already". They've spent the last several episodes developing this alien race and we still haven't met them yet.
Also, when they said that no Starship has ever left the Galaxy, The Enterprise did it in Star Trek 5. I think the only thing I liked about this episode was they finally made the Galactic Barrier threatening as promised in Star Trek 5. However, since we're at the end of the season and Picard starts in a week and I've actually started to get excited for the premiere of Picard, having this episode continue the stalling this season is doing is not good for priorities for next week's viewing.
This season is like watching a CW show and getting frustrated that ever since the Christmas Break there is a feeling of the show treading water until the last possible moment. The Flash was like this when we first met Nora and now Discovery is getting to be like this as well. Let's get on with it and start defeating this thing.
