Their having been out of touch for so long makes for an easy excuse for this sort of thing. They could either go in with some inaccurate assumptions or, more likely, to see if this thing they have no experience with is something they like or not.

There are almost certainly going to be things where they come out not having liked it, or only having liked particular elements but not the show as a whole.
