A mild complaint that I have is that the episodes are in a 10 minutes format, rather than a 21 minute format. If it were this way, I'm sure we would've had an episode explaining who Sticks was.
I think the two games are supposed to be prequels to the series. Sticks might be explained in those games.
I also watched the first episode and I admittedly kinda liked it. I was thinking "this is so silly" sometimes, but I didn't think it was terrible. But admittedly, I dunno if I'd be able to watch this if Dr. Eggman and his voice wasn't there. The other characters haven't been bad by any means and I did laugh at some of the stuff they did, but Eggman and his evil ham really holds it together for me.
