Director Jason Reitman does his father and fans proud with a funny, sweet, and spooky family movie that proudly takes on the legacy of Ghostbusters, while also introducing something exciting and new.

[Reitman] finds the perfect tone here . . . He’s also skilled at getting genuine performance out of young actors, as he proved in “Juno,” and balancing humor with stakes — essential for comedy-horror like “Ghostbusters.” The jokes are very funny and Wolfhard and Grace make life-threatening peril look like a ball.

It’s always fun, inventive and full of charm. If you have any concerns that Jason Reitman’s film might sully the legacy of his dad’s greatest creation, there’s nothing to be afraid of.

As franchise update, origin story, coming-of-age movie, comedy and indulgent f/x extravaganza, the feature, written by the director and Gil Kenan (Monster House), hits all its marks.

Warm, witty and full of wonder, Afterlife reanimates a franchise without spitting on its grave.
