‘Su’Kal’: Burned by the Burn
"Su’Kal" would be a reasonably okay sci-fi story in the standalone tradition of Star Trek if the circumstances were different. This is an alien contact within a holographic simulation that has some things to recommend, including notable atmosphere and characters trying to use psychology and storytelling to communicate with someone who has endured a lifetime of isolation. The problem is, this is tied into the season’s central mystery of the Burn in a way that’s crushingly disappointing. (At least, so far. Specifics are not yet revealed, although I can’t imagine any technobabble explanation could salvage this general idea.)
I’m reminded of DS9‘s "Extreme Measures," in which a big piece of the fate of the Dominion War was riding on a virtual-reality probe to explore the mind of Section 31 operative Sloan, but the device was mostly used as an excuse to give O’Brien and Bashir one last buddy adventure. The idea of one last buddy adventure was fine, but the vehicle was inappropriate and the timing was terrible.
