I just posted my review of the episode here:

What was odd about this episode, was how at one point it could be insulting and stereotypical in it’s portrayal of con goers, and then turn around and seemingly defend the fans.
That wasn't odd, it was simply observant on the part of some writers who've actually attended these conventions. Both the "overweight pale basement dwellers dressed in latex foreheads and crazy outfits" and "normal fans" abound at these things, and for the writers to represent a convention as being composed of only the "normal" kind would be as unrealistic as treating the whole of fandom as "galaxy class fans" clad in unforgiving Spandex. It would certainly leave out the possibility of shooting at an actual convention - as some of this episode supposedly was - without a lot of wranglers to keep the peculiarly-dressed and oddly-behaving fans out of camera range.
