I think this is the first time I see Selma as the main character in a Simpsons episode. Well, there is nothing wrong with that. This gives the show some fresh air and new angles. This is another episode that didn't make me laugh a lot, but it was so much better than the last fourth episodes in this seventh season. I really enjoy movie references and this episode had a couple that gave me very good laughs.
Poor Troy doing all kind of things to return to the top and this includes hurting other people's feelings. In the end Selma does what is right and this show us once again that not all the characters in the Simpsons' universe are not what they seem.
