A couple weeks ago, we reported that the ratings for the new Hawaii Five-0 were not as good as the network would like you to believe. It may have started off as the season’s most popular new show but that’s not no longer the case.

Hawaii Five-0 got off to a strong start with a 3.9 in the 18-49 demographic and 14.2 million total viewers. In week two, they dropped 8% (not bad) and in week three they fell another 3% (still not bad).

For the fourth episode, the ratings dropped an alarming 11% to a 3.1 rating and 10.7 million viewers. We heard from several readers that all shows were down that night. Not so. ABC’s Castle was actually up by 4%. Still, if Hawaii Five-0’s steep decline was indeed an anomaly than you’d expect the numbers to bounce back the following week.

They didn’t. The numbers fell another 6.5% to a 2.9 in the demo and 10.94 million viewers. This week, they fell yet again — for the fifth week in a row — to a 2.8 rating and 10.23 million viewers. It’s only a 3.5% drop but, for the first time, Hawaii Five-0 was beaten by Castle. The ABC show’s its biggest competitor in the timeslot while NBC’s Chase is always a distant third. This week, Castle brought in a 2.9 rating and 11.32 million.

Hawaii Five-0 is still not in immediate danger of being cancelled. As expected, the network recently gave it a full season and ordered nine more episodes. The lower the ratings fall however, the less likely it is to be renewed for a second season. One has to wonder when the ratings will finally stop falling or maybe even start going back up.

What do you think? How low will the ratings fall? Are you still watching?
