I love the 1st one. It has everything needed to make a great platform game. The other 2 were ok but I think they were realy just designed for kids who's parents wont let them play GTA. The gameplay was fun but not what it should have been if it is to follow up a more kid orientated game.
I gave up on the series. I really hate the way they have made a great platform game and turned it into a kids version of GTA and now the racing spin-off... I think it would have been better off as a kids game.
