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.

Sequelitis - Even the fans of the series generally admit that Carry On Behind is where the franchise began to fall apart completely.
