I would characterize Michael more by his self-righteousness and ego-driven attempts to be good than his actual goodness; so many of the show’s hijinks stem from his savior complex bringing out the hypocrisy in his attempts to be ‘a good guy’.

To be clear I think it adds to the humor, not complaining at all. Horrible people being horrible makes great comedy and Arrested Development offers far more than just that (probably my favorite comedy show). But it can get kinda depressing, if I’m not in a great mood I can’t take more than a couple episodes at a time.
