New Super Mario Bros./YMMV

The four games provides examples of:

 * Excuse Plot: It just wouldn't be Mario if it didn't have it.
 * It's the Same, Now It Sucks: Every game in the series invoked this reaction from people due to it being a 2D platformer, and it gets worse with every new installment.
 * Most Annoying Sound: The "PAH!" sound that permeates most of the music in the series.

The DS game provides examples of:

 * And the Fandom Rejoiced: it was the first 2D Mario platformer in 14 years. It was kind of a given that people were gonna be excited about it.
 * The sequel brings back the Racoon Suit, and you can actually fly again!
 * Angst? What Angst?: Mario (or Luigi) certainly doesn't have any qualms seeing Bowser get Stripped to the Bone after the first boss battle; they just say their end-of-boss phrase cheerfully and move on.
 * Crowning Music of Awesome: The Castle theme.
 * The overworld theme is pretty catchy, too.
 * The Platforms-a-Plenty theme from Super Mario Sunshine returns slightly arranged as the music for the Trampoline Time minigame.
 * Fridge Logic: Why does Bowser Jr keep screwing time waiting for Mario to beat each world boss to drag Peach to the next world when he could just run all the way to the last castle without wasting time?
 * And why did the creators have two levels inaccessible in the main storyline? How do we get to them?
 * Then again he's just a kid.
 * They ARE accessible, you just have to beat the previous world's boss while mini.
 * It's Easy, So It Sucks: A lot of people feel this way. Even Miyamoto has stated that he regrets making it too easy.
 * Power-Up Letdown: The Mega Mushroom looks awesome, but if you break a pipe, you can't go down it, ruining your chances of potentially finding a Star Coin. Also, the Blue Shell handles awkwardly with its sliding mechanic, though it does improve your swimming. The Mini Mushroom, meanwhile, lets you jump higher and with (much) floatier physics, as well as access certain areas otherwise inaccessible, with the drawback that it has zero hit points; one hit from anything will kill you. When you're going for all the Star Coins and have to use it in the later levels where things get hectic...all those lives you accumulated in the early levels are going to come in handy.
