Star Trek: Picard Review –
When you look back on Season 1 and Season 2 of Star Trek Picard, I loved them, but they did suffer from the mid-season slump. They got lost among the weeds but found themselves in the end. But this is the last ever season, and if you wanted something to land, now would be the time to do it, and I am so glad that is what we are getting.
So to set the scene, at the end of Imposters, we discovered that things were worse than anyone had thought. The Changelings can now replicate internal organs meaning they can pass through all the scanners set up at the end of The Dominion War. Now they have made their way into every part of Starfleet, and the USS Titan-A is now in their sights. How can they prove they are innocent? Oh, just infiltrate the most secure facility in all of the Federation. Now from here, we will be looking at the episode as a whole, so there will be some [SPOILERS] ahead.
