There's nothing wrong with a game being short. Many modern video game developers fall into the trap of extending their offerings with a ton of filler, which can prove to be a detriment for players who just want to enjoy the experience instead of being forced to trudge through hours of unnecessary content to get to the good stuff. This is why players love Nintendo games, with most of these experiences cutting out the fluff and ensuring that players are in for a wild ride from start to end.
