I had a love/hate thing going with this episode. I liked all the father/son stuff, but the Kryptonite baddie of the week was just laughable. Especially at the end when he basically breaks into a South Park "You know, I learned something today." That was an incredibly weak way to end the episode. As always Lex is the most interesting character, especially in the way he handled the auditor from his Dad. He's slowly slipping to the dark side, but apparently he knows it. Interesting.
