I definitely agree that Kathryn doesn't really add much to the show despite the fact that I very much enjoy Wendy Malik in general. I will say though that I thought the scene where she casually talked about reading Greg's book because he's her son-in-law and she likes to know what he's up to was very sweet (even if it was undercut by her launching immediately into another story about herself). Last season, we saw that Greg's own father was extremely dismissive of him writing a book, so it was nice to see that even self-absorbed Kathryn valued his accomplishments more.
Also, Franklin talking about how Soapdish of all things is the only movie he's ever watched (and then the later scene where Anna Kat is about to reveal her chosen movie and he says something like "I hope it's Soapdish") was actually pretty funny and probably the only laugh out loud moment of the episode for me. They generally utilize his character sparingly enough for him to consistently be funny to me
