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: Anvil! The Story of Anvil
Big In Japan: The opening and the ending. It's played straight. VERY straight.
Crowning Moment Of Awesome: The ending. The band open a big metal festival in Japan. They fear nobody is going to show up, as per usual. The arena is crammed full and Anvil end up rocking the house.
