Today my family and I finally got out to see Jumanji: Welcome to the Jungle, this season’s sleeper hit. Having seen it, I absolutely can understand why it’s found the success it has, because, yeah, it’s really very good.

The story has four teenagers – nerd, jock, popular girl, awkward girl – being sucked into a video game version of the Jumanji game (the process by which the original board game became a video game is a deceptively brilliant bit of writing: achieving what needs to be done with minimal fuss while simultaneously establishing certain key elements of the Jumanji entity). Inside they have to play as their respective avatars – played by Dwayne Johnson, Karen Gillan, Jack Black, and Kevin Hart – to complete the game and escape.

The concept of someone being pulled into a video game isn’t new, but it’s done with particular skill here. The movie takes full advantage of the situation, both to have crazy stunts and action (like having a helicopter pursued by a herd of rhinos) and for a ton of very funny jokes. For instance, the characters they meet in the game are NPCs, meaning they only have a few set reactions and lines of dialogue, which they will cheerfully repeat indefinitely if pressed. The characters each have three lives, a fact they make some very creative uses of.

I was very impressed by the writing. I mean, it’s not extremely smart or extremely clever, but they do a really good job of establishing these characters and giving them credible personalities along with their cliche types. For instance, the popular girl is established almost at once to be both very self-conscious and much smarter than she would seem at first glance, all in probably about a minute of screen-time. Their relationships are all entirely believable and human, as are their developments after they enter the game world.

Meanwhile, the four leads do a simply fantastic job of playing teenagers inhabiting video game avatars, especially Dwayne Johnson as the nerdy kid and Jack Black as the popular girl. I admit, I was a little worried about that element at first – it seemed like a chance for fashionable nonsense about gender – but no; it completely works in context, to the point where you simply accept the character as a girl playing a video game. This is another example of the film making full use of its premise: of course people often play avatars of the opposite sex, and if you were forced to ‘live’ the role, this probably would be the result. Plus, it’s just really, really funny; like an extended burlesque routine. It’s an example of taking an element of contemporary life and doing something genuinely creative with it.

And all the while, in all the over-the-top action and goofy humor, they still keep the focus on the characters and story. There’s a scene where Jack Black has to teach Karen Gillan how to be sexy: that’s funny on about three or four levels, but at the same time it’s also a key point of their character development, with the two of them opening up and becoming friends and the nerdy girl learning how to be more confident.

I also like that all the characters have something to teach and something to learn from each other. And that they all were, at the end of the day, what I would call legit heroes: at different points they were each willing to step up, sacrifice, and make hard calls for each other and for the greater good.

So, yeah, this was a really good movie: an example of really solid, well-done entertainment. It knows exactly what it is and wants to do and does it with energy and skill: exactly the kind of film that Hollywood ought to be making all the time.
