From the graphic novel series of the same name by Peter Lenkov
A dead cop wakes up in a police station, that turns out to be where afterlife cops chase dead guys trying to make them move on to whatever’s next, and of course there’s A) a big conspiracy that will End The World As We Know It and B) the answer to the mystery of the new guy’s death.
Oh man what a turkey. I read the graphic novels, and thought, hm. Maybe the movie is better…but no.
Basically, it’s a ripoff of Men in Black with a big dose of Ghostbusters thrown in for funny and gross moments. Ryan Reynolds and Jeff Bridges are in there trying, but the script really doesn’t give them anything good to go with. The worldbuilding is shaky, stuff seems made up rather than having a reason for happening, and by the end they’re all just going through the motions.
Skip this and do yourself a favor, watch MIB and Ghostbusters again instead. You’ll be glad you did.
