Everyone is praising this show, and with good reason, it is very, very funny. It is a shame that this show sticks out like a sore thumb on the schedule when most sitcoms aren't funny these days (except maybe "The Simpsons", and even that's not as good as it used to be), and the rest are mainly substandard dramas and awful "reality" shows.
Back in the 70s, the good vs. bad sitcom ratio was so high that some GOOD shows didn't even get a chance as they aired them at the same time on competing networks. There were so many good classics that are still good now like "Mary Tyler Moore", "Bob Newhart", "All in the Family", "Odd Couple", etc., etc.
My advice for "Earl" fans. Watch it now before they "dumb it down" or move it on the schedule 20 times (they've already moved it once) before they cancel it. I'm waiting for the second season to see if they keep the high quality up. They didn't with "Scrubs" and "That 70s Show".
