I thought this was another good episode from the 33rd series (yes, you read that right, 33rd!) series of the show.
It makes good use of a supporting character, with a plot that links them in nicely with the Simpsons themselves, and it provides some very funny moments.
It's all too easy to bash modern episodes of 'The Simpsons' and to compare them to the so-called 'golden era' of yesteryear, but there's a lot of good to be found in these latter episodes, and perhaps people should be more objective.
I personally thought that there was a lot of lovely moments to be found here, and enjoyed what I saw.
