I was never much of a fan of the cartoon (like the 3 previous ones before it) but have watched a fair few and I kinda liked the idea of the various themed worlds, though for the most part the characters didn't do much for me. Remember being very happy Thundercracker got his own unique toy, then watched the cartoon and he was some dumb hillbilly character which was off-putting. Was more of a fan of the toyline which brought us some great figures - I remember being very excited when I first picked up Primus and brought him home
