Ha, nostalgia for the good old days of TAR? Well, I have to agree those teams you named were more interesting than what we've been getting lately, although I will remember the doctors. But maybe the reality shows do round-ups because they're having trouble getting applicants (or acceptable ones they'd feel safe putting on TV).
A different show...Dexter didn't find his soul mate after all. A pity, in a way, but certainly safer this way. He'll still live out the rest of his life knowing there's someone out there who could reveal his, umm, "hobby" to the rest of the world.
