I have a thing for elevator movies, because what the hell would be more horrifying than getting stuck on an elevator? Well, probably a few things, but still. Jesus.
The obvious comparison here is Devil, the odd elevator/satan-among-us Dowdle movie. Similar scenes, dynamics, just lacking in the mildly interesting religious theme.
Here, the devil is, well, pretty much everyone. A cast of caricaturized stereotypes, most with an abrasively nasty personality, get stuck on an elevator after a kid decides to antagonize a claustrophobic man by pressing the emergency stop button. Kid is a total brat--she's not an exception to the "nasty personality" malady that infects most of the characters.
Everything gets stuck, no one outside seems to care much, blah…
