Jon Hamm is really not a fan of The Family Stone.

“Mostly because these are ‘required viewing’ for the holidays. It would be either Die Hard, or—and this is a weird choice, but we watch it almost every season—The Family Stone,” he tells Empire in an upcoming interview (via E! News).

“I find that movie fascinating. I think it’s an inexplicably weird movie. It’s got a rock-solid, jam-packed, stacked cast, but everything I watch it, I think, ‘This might be the worst movie I’ve ever seen in my life,’” Jon added.

The Family Stone does feature an impressive cast, boasting stars like Claire Danes, Diane Keaton, Rachel McAdams, and Sarah Jessica Parker, among others.

However, he then admitted that by the end, he “kind of” likes it.

“It’s unfathomable. I guess that’s what makes art, that you keep going back to it,” he concluded.

The Emmy-winning actor will soon return to television in season 2 of his Apple TV show Your Friends & Neighbors. Watch the trailer.
