How I Met Your Father is not a reboot of How I Met Your Mother -- it's a "standalone sequel"

TVLine

“People keep referring to the show as a ‘reboot,’ and it’s not a reboot,” said HIMYF co-creator Isaac Aptaker of his Hulu comedy at the TV press tour. “It’s set in the world of the previous show, but it’s really its own thing." Aptaker added: “That said, we love How I Met Your Mother,” noting that HIMYM co-creators Carter Bays and Craig Thomas and original director Pamela Fryman are all “very involved” in the making of HIMYF. Star Hilary Duff, who's a producer on the show as well, added: “I think it’s important to know that we are our own show… We’re trying to create something original (while) stealing a few things from them that worked really well.”
