"True Blood" fans are not happy the long-running vampire drama is coming to an end. However, leading man Stephen Moyer believes that ending the show in its seventh season is the right decision.

"I think they made the right call to say, 'Let's finish it on a massive run of 10 episodes,'" he told TVLine, adding that HBO considered extending the series to an eighth season. "It was either going to be one season or two seasons... and I would've definitely [stayed] on. But it's very difficult with a show like ours to keep finding a Big Bad and creating all the drama around it."

Moyer, who is starring alongside Carrie Underwood in "The Sound of Music Live" Thursday, said he isn't privy to many details about what showrunner Brian Buckner has planned for the 10-episode final season. But, he said he does know that the ending will be bittersweet.

He also said that despite the audience's perceptions of his character, Bill, he loves playing him.

"The characters can't [always] be who the audience - or the actor - wants them to be at all times. That would be dull. A bunch of people loved Bill and Sookie together, but a whole bunch of people didn't. So you can't just please this bunch or that bunch," Moyer said.

"And I've always said, as soon as you see one of our couples get together, you know [they're] f-ed. As soon as Hoyt and Jessica got together I was like "No! They're going to f-ing kill this, I know they are!" he continued. "Because [that relationship] was so beautiful... I loved playing [Bill]. I love him. Whether they're were things that I feel were done well or badly or right or brilliantly, I love him."

Although Buckner hinted that the last season will focus on the love triangle between Bill, Sookie and Alcide, Moyer said he does not know any details. Moyer will direct the season's first episode, but he has not yet seen the script.

He said he doesn't know if Bill and Sookie will end up together, or if Bill was simply a "window" into Sookie's new world.

"I don't think that there is a right or wrong answer," he said about the pair potentially ending up together. "I think a bunch of people would be happy if that was the story and a bunch of people would be pissed off if that was the story. I don't read that s-t, so I don't care, ultimately. All I want to do is do the show and have fun doing it."

He also said that he will be sad to leave his "True Blood" family.

"Around Episode 4 or 5 [of every season] we always start getting panicked about that season ending, because it's a f-ing family," he shared. "That word is bandied about a little bit too much, but it really does feel like [a family]. I'm going to be very excited about what's to come [career-wise], but slightly bereft that it's all going to be done."
