My 2 boys at 4 and 7 are gonna love it as they love all kart-racers & Ben10.
And what's up with you kids (I assume you're in the 14-18 range from your comments) talking crap about it? So you've just outgrown Ben10, big deal!
The world is full with kids who'll love it, it's just not aimed at you. Guess you'll get the point in a decade or two...
