Fairly sure that part is from Schisms where Riker and other crew members are being abducted while they sleep by aliens. At this point he knows he’s going to be abducted and has taken some stimulants to stay awake so he decided to get abducted in his uniform rather than his sleeping clothes.
I also think it’s fairly weak overall but there are some really great outstanding episodes. Blink of an Eye, Counterpoint, Scorpion, for some examples. And I also agree that the worst Voyagers are really very bad, but are they that much worse than other series’ follies? Is Threshold worse than Code of Honor? Sacred Ground worse than Turnabout Intruder? Fair Haven worse than Profit and Lace?
