Lethal Inspection is the best yet. Maybe there is hope for the show after all. I was a bit wary when I saw the Star Wars references in the first couple of minutes. But it was just a brief nod to segway into an original and entertaining episode. My favorite episodes of Futurama are the ones with heart. The episode with Fry and his dog, the one with Fry's brother, The Devil's Hands are Idle Playthings, etc. Lethal Inspection sort of falls into this category. There are very few animated sitcoms that are capable of drama. Hell, there are very few sitcoms that are capable of drama, animated or otherwise.
Good episode. Hopefully it's uphill from here.
