Is The Simpson Dying?
9 March 2008 | by (Ireland) – See all my reviews

This latest season has been disappointing, and this latest episode is possibly the worst I've seen. It just didn't seem to gel together at all. Its almost like two different writers sat down and wrote half an episode each, then the two scripts were edited together by a third person.

The stories (2 different issues running) just weren't funny. Nor were the stories connected in any way. Firstly, Homers story could have been much better, if this was the only story in the episode, the only laugh i got was from the 'Lamb/Motel' scene. Bart, Lisa and Martins story was completely lacking in humor. And the 'Butterfly' ending was just weird, WHAT happened to this brand? Maybe 19 seasons is just too many?? Please Matt, bring back Futurama!!!!!! Even if Fox won't touch it, there are other networks man
