The wrongest opinion, regardless of however you feel about snaking.
EDIT: To elaborate, Mario Kart 7 and Mario Kart Wii are seriously the most pedestrian "wacky" racing games every conceived on nearly every level. GBA and the original Kart at least have the excuse of limitations to their hardware making the tracks not age well. Mario Kart 7's original content is basically awful. Out of the whole stable, I can remember ONE track in Mario Kart 7 that I can think is amusing. There's too much dead space in the tracks, and outside of using items, they are not interesting to race on whatsoever. The lack of being able to trigger your own dashes means that there's too much time spent just...going forward. Going straight, and hoping you have an item you can use defensively. Oh, and you can 'trick' off of things, which is the most anemic 'feature' put into the series. Where as in MK64, DD, and DS you could feel like you completely 'owned' your race and time trial by your own skill and experience, 7 is a less demanding gameplay experience to a series that honestly isn't very hard to get into. The only more boring MK title is Wii, which ought to say something.
There's more! Regardless of whether or not you play in single player (which you should to unlock decent karts) or play in multiplayer, the item balance in 7 is all kinds of bad. It's not quite the same as outright rubberbanding (though 7 has plenty of bullshit regarding the speed of rival karts on 150 cc/mirror), but it is pretty amazing to get hit with three blue shells in a row, followed by four red shells and a perfectly aimed green shell before winning the all cup mode.
