Forgive me for not believing the reviewer, but this sounds like a petty and meanspirited tantrum to me.
Actually, I think this reviewer is attempting to be as nice as possible. :)
I just realized you were talking about the show! (Not the review.) And, yes, it probably has some jokes aimed at Jenna Bush, but perhaps in a good natured -- and not mean-spirited -- way. I am just guessing.
