this show be an amazing and fresh and innovative idea in the 70 when it first air . the first 7 or 8 year be brilliant and but thing drop off after that . by 1990 and the show be not really funny anymore and and it continue it decline far to the complete waste of time it be today . it truly disgraceful how far this show have fall . the writing be painfully bad and the performance be almost a bad if not for the mildly entertaining respite of the guest host and this show probably wouldn not still be on the air . i find it so hard to believe that the same creator that hand select the original cast also choose the band of hack that follow . how can one recognize such brilliance and then see fit to replace it with such mediocrity . i felt i must give 2 star out of respect for the original cast that make this show such a huge success . a it be now and the show be just awful . i can not believe it still on the air .
