I thoroughly enjoyed the game, but I thought that ending where we're forced to see her run with all of Wario's hard-earned loot is really, really bad. It's not funny, and it makes Wario sound like some silly cartoon villain who is to be laughed at. That, and Wario has always shown to be superior to Syrup throughout the series (especially in the "Captured Syrup" branch of the Wario Land 2 story), and all other Wario Lands end in a good note for our hero with him getting lots of loot.
Anyone else strongly dislikes that ending?
