After the success of the sleeper hit Jumanji: Welcome to the Jungle, it was only a matter of time before a sequel got made. Jumanji: The Next Level is pretty much Welcome to the Jungle all over again. It's a fun movie, it's cleverly written, and that's about it. It covers many of the same beats, but it's still funny because the premise is something that can be used for a whole new set of different jokes and gags. Spencer goes back to Jumanji, and the others need to get him back. Only this time, Spencer's grandfather (Danny DeVito) and his business partner (Danny Glover) get sucked in too. At the beginning, Danny DeVito is in the Rock's body, Danny Glover in Kevin Hart, Fridge in Jack Black, and Martha returns to Karen Gillan.
The main source of humor is people adjusting to being in different bodies and having different abilities, and it is based on the idea of people ending up in the bodies of people drastically contrast with who they are as people. The reason it works is that the audience is somehow able to see Danny DeVito as the Rock, rather than the just Rock acting like an old guy. It's a difficult thing to pull off, and it does so successfully. While the idea of the old guys adjusting is funny at first, it does get old after a while. It funny enough on its own to make it a good time. Much like the previous movie, it carries a strong sense of adventure. It does end on a sequel hook, so Jumanji 4 is inevitable at this point. Based on this and WTTJ, we can imagine it's going to be a fun, entertaining, and enjoyable.
