give shows a chance

these networks are too radical and give up on shows too quickly. if mash, cheers , and hill street blues were on today they wouldnt make it out of the first season. star trek wouldnt have become a national phenomenon and im sure there are countless successful shows that had bad ratings in the beginning. this was a good show. how can it be judged by only 3 shows. they didnt even give it a chance yet crap like cavemen(i want the 10 minutes of my life i spent watching that garbage back)stays on the air
