THE ENDURING APPEAL OF FIREFLY.

Firefly” aired for only one season 10 years ago, but Nathan Fillion still hasn’t gotten over it.

“It was the best character I ever played,” Fillion told The Post. “The best dialogue to ever come out of my mouth was on that show.

“It was my first time truly being in love with my work,” he says. “It’s the bar to which we compare every job.”

I’m beginning to think, though, that in real life Joss Whedon would have been on the side of the Alliance.
