Query: Less human enemies and keeps on being great

The first season annoyed due to the human enemies and not enough robot action. The second season introduces the Elite Guard, which is pretty awesome in itself. There is even an episode that develops Bumblebee's and Bulkhead's background, which I thought was nice.The characters all have personality, whether Autobot, Decepticon, or human. This series has action, comedy, and some drama.I do not wish to spoil anything, but this series is a great series and keeps improving as it goes along. (The third season has also started, so do not miss it!)
