Another thing: Teledji is just such a terrible villain.

Everyone else got some kind of buildup and characterization. For him, though, we pretty much had it dropped in our laps, "Oh hey remember that guy? By the way he's evil" and he was evil. Terrible example of telling rather than showing.

And the only piece of him we got past that point was just ludicrous mustache-twirling cartoon crap.

Gaius had tons of nuance and gave off a believable sense that he sincerely felt that he was the hero of his own story. Nael was entertainingly warped. The Ascians are fun to watch for their constant need for amicability while carrying out full-scale supervillain projects. Even Lolorito gives off a sense that his callousness is borne from world-weary cynicism rather than psychopathy, adding potential layers. Teledji? He's a bad joke.
