A rare misrating by Netflix's algorithm; it thought I'd love it. I thought it was boring, predictable, and stupid. Or maybe I was just in a bad mood. I don't claim that these reports are anywhere near objective measures of movie quality.
For the record: I liked the old Jumanji movie just fine. I like Dwayne Johnson. I even like Jack Black. Rhys Darby was hilarious in "Flight of the Conchords". Kevin Hart is OK, I guess.
I even like Karen Gillan, who played Nebula in recent Marvel movies, although I didn't recognize her with hair and non-blue skin.
Anyway. It's the inverse of the original movie; instead of game characters showing up to menace the real world, kids are sucked into the game-world. They show up as adults, although still have their kid personalities. So they bicker childishly, and doubt that their new bodies can accomplish what they need to do to win the game.
Yes, the kids are misunderstood losers and outcasts in the real world, and are tossed together by getting detention.
I fell asleep at a number of points, so maybe good stuff happened then.
