The official editorial review neglects to mention that although this DVD is titled as "Season 4" the episodes actually ran in two seasons. In season 4, the show was quite frequently pre-empted when Fox's NFL Sunday Night football games ran long. Those pre-empted episodes aired the following season (so-called season 5) after the show had already been cancelled. It can not be said that the show did not get a wider audience because of too many in-jokes, or that it contained too much sci-fi to appeal to non-nerds. The fact is that in season 4, it was difficult for even die-hard fans to actually catch an episode. The kicker is that just prior to season 4, it won an Emmy for best animated series.

There are a few stinkers on this DVD, but not significantly more than in the previous seasons. Futurama got funnier each season, period.
