The final seven episodes of AMC's Mad Men will air in 2015, but series creator Matthew Weiner admits that not everyone will be pleased with the show's conclusion.

"The road has been paved for a mixed review, no matter what," Weiner told Rolling Stone on Monday. "I do what I've always done on the show and rely on the people around me."

There have been plenty of conspiracy theories regarding how the show will end. Weiner knows this, but he has tried his best to let to it conflict with his vision for the show, noting that he's treated every season as the end for fear the series would not return.

Now that the program is truly ending, things do feel a little different.

"It's very bittersweet," added Weiner, "And high-pressure."

The pressure has indeed proved to be intense for those involved with the series. While some, like Weiner and actress Elisabeth Moss (Peggy Olson), have headed straight into new projects following the end of production, actor Jon Hamm (Don Draper) has decided to take his time.

"I'm taking some meetings on projects, but mostly I've been in chill-out," the 43-year-old star admitted in DNA Tuesday. "I've enjoyed it, and I think it was warranted. I worked hard for eight years. I know some of my cast are on to other projects, but I'm too old for that."

Mad Men returns to AMC to finish its seventh and final season in 2015.
