After a slow start, it grows on you fast. As more characters get fleshed out and added, you enjoy the campy 60's superhero style over-the-top acting more and more. Reminded me of watching Adam West as Batman, but The Tick even takes that up a notch.
Dot was the one I most enjoyed watching come into her character. She totally should have told Overkill he was a lousy shot on the rooftop.
