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.

They Wasted a Perfectly Good Plot: So Rise of a Warrior gets Randy Couture as the Big Bad for an entry in a series that is known for having some pretty awesome melee fight scenes.
