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: John Doe
Jumping the Shark: During most of the series, the protagonist/narrator voice insisted that there was nothing paranormal about his abilities. The last couple of episodes before cancellation showed that this wasn't the case.
When Karen was killed , ironically her looking for supernatural answers kept the plot grounded.
