No doubt Season 5 will be a major challenge for Leary and the other writers. I know the season will have low points since no show I've ever watched can come up with killer episodes for a 20-26 episode season, see: MASH, WKRP, Cheers, Hill Street Blues, Taxi, The Honeymooners, King of the Hill, early Simpsons, Mary Tyler Moore, Seinfeld, Family Guy, All in the Family, Battlestar Galactica etc...
