It's a fun game with decent music and controls, and it does a great job of demonstrating what the Wii is capable of. However, it's pretty easy overall and has relatively linear paths to play by, leaving little room for replay value, and making it a very short game for experienced players. I can see why some people were disappointed while others think it's outstanding.

In other words, while it's a good game, yes, it's a little over-rated.

the game is perfect it cant be improved

no game is perfect, they can all be improved

1. More Playable Characters
2. More Interactive Multiplayer.
etc.

understand?

Playable characters aren't the issue here but the Multiplayer could've been improved even though it's an Adventure game and it doesn't really need one.

They had plans to incorporate a racing-like element but they scrapped it, unfortunately..

exactly, no but the point i was making was that a game can always be improved and is never perfect which shadow specified
