For fans of the new CBS series "Extant," you should be aware that the network is moving its air time up an hour, from its current 9pm time slot, to 10pm on Wednesday nights.

Why? Well, after a strong 9.4 million total viewers debut, audience draw has gradually slipped since then, to around 6.5 million viewers – quite a significant drop-off, after just 3 episodes of what is expected to be a 13-episode season. So CBS is hoping that the later time-slot, which will give the series a lead-in from "Criminal Minds" repeats, will help raise ratings ("Big Brother" is the show’s current lead-in). And maybe more importantly, it also means that it won’t compete with Fox’s "So You Think You Can Dance," and NBC’s "America’s Got Talent," which also air on Wednesday nights at 9pm. 

There’s less competition during the 10pm hour on that day. 

The move to the later hour is effective immediately, starting with this week’s episode, tonight, Wednesday, July 30.

Despite its 9.424 million viewer debut , expectations were apparently for a higher figure, as analyst compared it to ratings for CBS’ last big summer series debut, "Under The Dome." "Dome" drew 13.14 million viewers a summer ago.

Then again, one could argue that, even in just a single year, our TV viewing habits have changed (and continue to change), affecting how much live TV watching we all do (you can thank binge-watching for some of that shift; it’s certainly had an effect on me). 

Still, 9.424 million viewers is nothing to sneeze at. 

I’ve watched all the episodes thus far, and, as I said after episode 1, I’m sadly still not hooked. I’m certainly not turned off either, but it’s just not the kind of must-see-TV I expected it to be – at least, not for me. But I’m sure it’s working for a lot of you.

However, I’ve stuck with it for 3 episodes, and will continue to do so for a few more.

In "Extant," Halle Berry plays a female astronaut trying to reconnect with her family, when she returns home after a year on a solo mission in space; her arrival back on earth comes with the realization that she’s carrying what is likely an alien baby (or something). 

Sergio Harford, Goran Visnjic, Louis Gossett Jr., Grace Gummer, Camryn Manheim and Michael O’Neill all co-star.

The script was penned by Mickey Fisher, who is executive producing alongside Spielberg, Greg Walker, Brooklyn Weaver, Justin Falvey and Darryl Frank.
