We live in an MTV world! Hour long sitcoms lose audiences quickly. We want humor in short, frenetic bursts. The "Malcolm" pace would not have held up for more than 1/2 hour. It's not that the material wasn't good enough ... it's that the audience isn't patient enough. Look at feature films. Dramas can go on for hours. Comedies cannot. It's just one of those things that make you scratch your head. Also, comedies rarely get nominated for Oscars ... but don't get me started on THAT one!
