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: Super Mario Bros.: The Lost Levels
It's the Same, so It Sucks: Wasn't just a fan reaction. The #1 reason Nintendo decided not to export the Famicom version to the US was that they didn't think such an obvious Mission Pack Sequel would sell well in the States (note that simply being Nintendo Hard didn't stop them from exporting any other games back then).
Painful Rhyme: The poem you get after beating 8-4, which also appears in Vs. Super Mario Bros.:
Peace is paved/With kingdom saved/Hurrah to Marionote or Luigi, but that breaks the rhyme/Our only hero/This ends your trip/Of a long friendshipnote 100000 pts. added/For each player left.
