Family Guy has been in a decline for the last couple of years. The problem is that for every original or surprisingly intelligent joke, there are several instances of them going back to recycle bin in the worst possible way. Those ways are, at the very least, animating blood because the writers think innocent dead things are funny, and the increasing stupidity of Chris and Peter. This episode featured a mix of the good and the bad, as Peter, Joe, Quagmire, and Brian wake up, with amnesia, in a deserted Quahog.
The stupidest thing about this show now is the plot holes because even for a show like Family Guy there is a limit to how dumb is too dumb, such as the gang not figuring out who they based on reading tweets, and no one figuring out that Peter's newspaper picture was a prop. In real-life, or a better cartoon, these issues wouldn't have even been issues.
The other problem is the lack of character development. Is it wrong to want character development from a show like this? I remember the episode after Peter said he would cut back on drinking, he came out of the Clam hammered, it's ridiculous. This time we get what should be something of an important moment between Peter and Brian, but next week I'm sure Peter will kick Brian's ass in a non-cutaway. It's just a problem the writers and producers should worry about if they want to attempt to hit the 500+ episodes of "The Simpsons," or just not make people angry they decided to watch Fox on Sunday.
What didn't save this episode, but helped, was the fact that a lot of the jokes were good this week. My favorites were the return of "Surfin' Bird" and Who Else but Quagmire, the tour of Quagmire's house and Joe thinking he's a stripper. Other great jokes were Stewie's cutaway about the girl's best friend and the final moments of the episode after the amnesia is explained.
In all, this episode is at least worth re-watching if you can ignore the worst of what Family Guy has become. The whole series isn't terrible yet, and hopefully before it's booed off the air, things can magically turn around for the series.
