Hall was definitely creepy - I'll give him that. But, I think the main difference between the two Willies is depth and talent. Karlen has it and then some. Hall's acting ability, at least at this point in time, appeared to be hovering somewhere at the Jr. high school play level. Hideously stiff, stammering delivery which actually made me feel a little embarrassed for him. I hate to sound harsh but, we all have our talents and acting was not one of his. I really hope he found his niche in some other line of work. At least he had the guts to give acting a try - which I would imagine takes a lot of nerve and a very tough skin. As to his little stint on DS, I have the feeling had John Karlen not taken over the role just when he did, Willie may have disappeared into the night - and few people would have noticed or lamented the fact.
