Context: my parents had the bathroom redone about a year ago (actually, almost exactly a year ago, as the project was about 4 days from complete and was interrupted by the first pandemic lockdown.). The ridiculous, fancy toilet seat they purchased has since develloped cracks in it and needs to be returned. Dad simply could not get the seat off himself... and see previous shout.
How to ruin somesones day with one question: Let someone work on a problem for about an hour and a half on their own, come to the realization they need an extra set of hands, ask for help, show you the problem and outright difficulty of it: then ask them "Hey, what does this button do?" and literally solve the two man dilema without doing any work.
As far as the TNT move, all of Season 5 was basically epilogue, which didn't help - when it looked like things were ending at Season 4 JMS tried to cram all the major plot threads for his original Season 4 and 5 plan into Season 4, which didn't leave them as much to work with for Season 5. Then TNT totally screwed with Crusade and got it killed before it got a chance to hit the real plot and nothing else really resonated enough to get a series push. A Crusade revival would be the best "B5:TNG" option IMO.
