These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Genius Bonus - The morse code at the beginning of every episode spells something out, which also counts as something of a Couch Gag.
Growing the Beard - The second half of season one, in many viewer's opinions, once the characters stopped behaving like idiots, the drama became dramatic, and Emily got significantly less screentime.
