Well I've finished watching the first 6 episodes of Season 2. While still not my favorite cartoon (and certainly not my favorite toyline) I will say that the show continues to improve. Having Optimus heading a stealth strike-force gives the show a bit more range and having the permanent Autobot cast expanded from 5 to 10 works well. Would be nice if Jazz came back to make it 11.
The Cons they fight are still for the most part a bit too stupid for my liking, but the former actor within me did quite like the persona they gave Overload. I've got the toy and to be honest I thought he was just gonna be another big angry bruiser. And the fact there is a whole new crashed ship full of Cons means that with the expanded Bot roster we might see some actual battles down the line instead of just fights.
In fact I think I've just pinpointed my problem with smaller casts such as that in BW, BM, Animated, TFPrime etc. With smaller casts you never have huge pitched battles like we saw in G1 and the Unicron Wars trilogy. You just have rumbles.
