The demo might have been easy, but I thought it would be a perfect game for a much younger audience... heck, I might even rent it just because I am such a fan of the first movie.
(That, and the achievements should be interesting!)
All things considered, I thought it was really fun to play this game. Seemed very true to the movie series... voice acting wasn't horrendous... and the cutout puppet show introduction was the perfect choice for this particular game.
It was really fun playing as Puss n' Boots... that, to me, could be worth the time to play this game when it comes out!
