A bit more subversive at times than expected while still fun for the family, Jake Kasdan’s Jumanji: Welcome to the Jungle (B) is ostensibly a riff on The Breakfast Club if detention were actually a fantasy forest of video game characters and its ensemble of aimless teens transformed into avatars on a quest for their inner heroism. After a sluggish start, the film gains its footing once the characters start learning life lessons in and around thrilling action sequences involving animal stampedes, helicopter chases, encounters in exotic marketplaces and a subplot involving a stolen jewel. The film makes compelling use of its gaming conceits as characters discover their powers and vulnerabilities and preserve “lives” for the moments that matter. As far as characters go, Dwayne Johnson and Nick Jonas fare best with charisma in spades, and Jack Black sinks his teeth into the role of a female teen diva learning to care about others while adapting to her new male body functions. Kasdan finds the fables behind the fun and makes sure the escapism leaves everyone a wee bit wiser from the journey.
