What I mean is that Hurst's Robotnik seemed evil to a his own detriment, ie. it made him incompetent. He seemed the type of guy who would drop all his well timed plans just to drown a nearby kitten. Evil and competence are different things, which is where the Villain Ball comes in.
Season One Robotnik was incredibly ruthless, but he was also an unnerving because of how tactful he was, he was genre savvy enough to just shoot Sonic (something Season Two Robotnik repeatedly turned down to savor the torture, which always led to his failure) and could even stand to be slightly pragmatic if it benefited his goal, ie. he stole from Lazzar, but via smooth talking his servant, and didn't waste time rubbing salt into the wound to risk the plan. Robotnik was deadly because he had no restraints or conscience, but also because he was incredibly tactful.
I think it was the Season One depiction that also worked a lot better into his background, Robotnik was intended to shrewd enough to deceive an entire kingdom into thinking he was a good guy for a lengthy period of time, and was tactful enough to hold onto his reigns for an entire decade. As proven by instances such as Game Guy, Season Two Robotnik couldn't last so much as a day without revealing to one of his patsies he screwed him over for kicks and was making increasingly detrimental mistakes that make you wonder why it was taking so long for Sonic to get the better of him (notice how easily Sonic neutralized him in his lair in Sonic Conversation, was there any reason he didn't take him down at that point?). He was beginning to look incompetent because he had no restraint, which even when you're not a 'noble' villain, is necessary in terms of basic plotting and deception.
Add to that Satam Robotnik was more sinister, but he was still an egotist, and egotists thrive on attention and respect, even in a skewed way like forcing people to do so. It made sense in Season One, he applied sentience to some of his robots (along with his pet Cluck who seemed incredibly attached and dependent on him), the robians seemed more brainwashed civilians and he even had some slight lenience onto Snively that he actually was loyal and even to some degree looked up to him and thrived on his rare approval. In a way he seemed to value some form of life, but one completely stripped of all the unnecessary complexities that didn't revolve around himself. Season Two Robotnik's motives seemed basically to make him the only sentient life on earth, even Snively seemed despensible to this ultimately, despite as shown as instances such as Cry of the Wolf, his endless insistence for someone to praise him and his work. Robotnik does not seem someone who could last without some sort of life worshiping the ground he works on.
While I know Satam Robotnik is a guy with no redeeming aspects and pure evil, he is still intended to be a character in a story, and his actions have to keep validity to this. There is more to a truly evil and effective villain than just kicking the dog non stop, and at times it felt like Hurst forgot that. I feel the vamped up treatment of robotocization was just another attempt at him making Robotnik look more vile, but not thinking how much suspension of disbelief could hold Chuck shrugging off the whole ordeal (which itself kinda undermines the point anyway since it makes the blow look like nothing).
