I like your ideas. Though to be fair, I don't know if when Alan began the show it was going to be an ongoing thing. It seemed like it was just a bunch of Zoom reunions while everyone was in lockdown to bring some cheer to all. They had much more of a spontaneous feel.
I will give credit to Alan for consistently getting good guests. But he still needs to work at actual research and interviewing skills.
Soap characters hook up with their exes’ siblings all of the time but it didn’t help matters that the show kept pushing how similar ED’s Kelly was to Eden when they never were before. It just made it more creepy.
