Yes, but I do think it is rather odd to ask people who are watching a show that is airing right now why they are watching that instead of a show that aired several years ago. It's like asking someone who is watching SGA why they aren't watching Enterprise instead. They may well have already watched the first show! And even if they haven't, one of the is sitting right there on basic cable and one of them...isn't.

(Also, to be honest, if I liked a show and someone said to me, "Why the hell are you watching that shit? Don't you know it's a cheap ripoff of Far Better Show? Why aren't you watching that instead?" my likely reaction would not be, "Oh, thank you ever so much for enlightening me, I will now renounce this show that I *thought* I was enjoying and go watch the show you deem to be far superior.")
