This isn't a long fic, so this won't be a long review. Ami-chan's Bad Day is a short one shot fic, detailing a good day gone horribly wrong to Ami. While the story has a few flaws, like unneeded Japanese and a notable lack of descriptions in a few places(Usagi being hit with Ami's Rhapsody was notably thin), it overall does what it needs to. It's funny and amusing, and for a short fic, that's what really matters.
