Tom kinda did the 20th century references thing with his automobile and b&w scifi obsessions. Perhaps he subonsciously missed Silverman?
Also, the elephant in the room when it comes to fish-out-of-water characters that gets "too much" focus is Seven, right? I mean, overall I like her a lot. And overall I appreciate the focus on her. When it's not corny or forced.
