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.
YMMV: Life With Derek
Acceptable Targets: The show preserves the grand Canadian tradition of making fun of Newfoundland.
Which could actually be a bit of an in joke, considering that that's where the first season was actually filmed.
Alternate Character Interpretation: The animosity between Derek and Casey is just as easily explained by their being two Type-A personalities competing for dominance in the household.
