Train to Busan. By a mile. Best zombie movie hands down. I’ll die on this hill.
Honourable mentions:
OG Dawn of the Dead is special and will always hold a top spot.
28 Days Later & 28 Weeks are both top notch.
And I’ll catch heat for this, but World War Z is an excellent zombie movie. And I say that as a fan of the book who is disappointed we didn’t get a faithful adaptation. But if you take the movie as a stand alone, unaffiliated, zombie flick, it’s better than just good.
I don’t think there is a James Bond origin story. So it would be original and not a reboot.
