No, it's how the tracks are design. 

It's an odd phenomenom that the GC and its software gets so much praise on the internet, but it comes down to three reasons:

1) The majority of the internet gaming community is made up of 15-20 year old gamers. This means the GC falls right into the timeframe when these gamers grew up which in turn means that everything during that time left stronger and more memorable impressions on them.

2) The majority of the internet gaming community takes pride in being hardcore and the GC doesn't have casual stench attached to it. As a rule of thumb, the hardcore must praise unpopular things and spit on popular things. The hardcore don't want to be thought of as sheep that go with the flow. Playing the same games as the masses is only deemed okay when the hive mind allows it which ironically makes the hardcore more sheepish than the masses who play the games they want.

3) There are also people that you can clearly identify as not real Nintendo fans who seemingly are in love with the GC. That is because Nintendo stayed within their box and left the market to the big boys. Nintendo is accepted as a hardware manufacturer as long as what they do doesn't interfere with the rest of the industry. The Wii U is set to follow the GC's footsteps, it's just that right now many of the hardcore are still confused by its name. They think it's a Wii successor when it is in fact a follow-up to the GC. Once that has dawned on them as well once it's set that Nintendo won't have much of a market presence in the home console space, we should begin to see more praise for the Wii U and its exclusive games (perhaps in 2016). Right now we are still in a period of fear that Nintendo could turn around the Wii U, hence why a topic that asks if games like DKC or SM3DW are system sellers is answered with a "no".
