My Sweet Alex O'Loughlin

Moonlight is a beautiful and unique show, but according to an article posted on TV Overmindn "It was ahead of its time"

CBS was "out there first with vampires", but they were the first which cancelled a vampire's show...

... Vampires didn't really hit it big until late 2008, with the premiere of True Blood and the release of the Twilight film. Moonlight ended its run in May 2008, barely missing the craze that would later make The Vampire Diaries a hit.

...

... In fact, they've been looking to see what they can do to fix their mistake — and that means talking to the cast.

...

...CBS wants to keep O'Laughlin on the network, and bringing back Moonlight is definitely a possibility on that agenda. “We love [Alex] and want him to stay around for a long time,” Tassler confirmed.

...

But is the Moonlight comeback a possibility? Possibly. Tassler stated that Moonlight's executive producer Joel Silver has discussed a potential return of the series with her, "but we talk about a lot of things," Tassler told Fancast. And even if the decision is made to bring back Moonlight, it wouldn't be immediate. "We’re about to pick up all of our [2010-11 season] pilots,” Tassler stressed, insinuating that Moonlight wouldn't be back before the end of 2010.

...

Of course, the big question that remains from that is: will that be too late? This vampire craze — some might call it a fad — has already lasted a year and a half, but how much staying power does it have? Will we be looking at a possible vampire recession before Moonlight has a chance to regain its footing — or even come back at all?
