This show always finds ways to surprise me. In fact, until this series, I was never a fan of Reba, although I liked her in Tremors, where her comedic sense first revealed itself. This series changed that for me. This episode, Have Your Cake, is one of the reasons why.
Don't get me wrong here, while most episodes are somewhat funny, they are not what I would consider exceptional. Nonetheless, this episode is an example of what they get right. Besides the usual decent humor, they manage to do an exceptional job of discussing women's "body issues" Keep in mind that I am a man, and so my understanding of these things might be limited, however, although it may mostly be thought of as an issue for women, men too have similar issues.
(Not me, of course, as I have the body of a Greek god LOLOLOL0L)
Reba's handling of her friend's self-esteem issue near the end is sensitive and thoughtful.
I strongly recommend this one if you'd like to see what good qualities there are in this series.
