I've been watching this series a lot lately.
I like how everyone always points out how idiotic it was to have "end of session music" like Doctor Katz did.
You're right, Don Irrera was probably the best fitting guest. He actually took advantage of the "therapy" angle of it.
I know some people didn't like the addition of Todd, the video store clerk, in the last two seasons, but I thought his scenes were generally pretty good. It makes sense that Ben would rent videos almost every day and get to know the video store clerk. It's not like he has anything else to do.
I also thought Dave Chappelle's session about Aquaman was pretty good. Usually his acts are just rants about black people, but his Doctor Katz episode was actually pretty funny.
If you liked Home Movies, get this. It's just as good, possibly even better.
