Great show that ran too long. First four seasons I rate 9. Consistently brilliant writing, great ensemble cast, many laugh out loud scenes. But it's very difficult to maintain this level of consistency year after year. Cracks start showing in season 5, but there are still plenty of good episodes, rate it 7. Seasons 6 and 7 take a nosedive as the writers run out of ideas and the comedy degenerates from witty fun to just plain stupid, rating drops to 5. So I give the show overall rating of 7.
