For a moment I think i was going to see a great movie, the first minutes are very well developed and the music and effects are very well put together in the right moments to create tension and panic, but... the movie shortcomings are way bigger than the good points.
Minor spoilers ahead...
For starters, character inconsistencies. The characters turn from heroes to whiners from one second to the other, we have some kind of creepy 13 years old girl who, BY NO MEANS, unless is possessed by the devil itself will laugh at this tragedy or will try to press the buttons of the elevator when SOMEONE is trying to get out!
This, it is simply not credible and in fact, ridiculous, unless of course we're talking with Carrie here.
We have a terrible claustrophobic comedian guy who after the elevator is stopped, suddenly it's decease disappears and then decides to behave like a hero.
We have a coward who sleeps with other women that tries to force the escape in the most possible stupid way because he too decides to behave like a hero.
I could go on and on and then we reach the second biggest flaw of this movie.
Forced situations with no explanations
1 hour stuck in the elevator with the head of the corporation in there and NOBODY respond to this guys when they ask in the alarm button, NOBODY, in fact, they just leave and do not answer, NOBODY TRIED to reach them and try to get them out, even BEFORE there is any sign that there is a bomb in the elevator.
They are basically left stranded with no outside help even when we are supposed to believe that this is getting in the news of the world!
This addition of inconsistencies turns this possible great movie in the first act into a totally insane and dumb movie in the second act.
Last point, decisions. The decisions taken by the passengers are beyond stupid, in one point one of the guys just want to go out of the elevator to press the external button so the elevator can move, he is in the top spot and he just decide to press the "down" button? YEAH RIGHT! I WILL DO THAT TOO, If I wanted to be cut in half!.
If the bomb is not sensitive to movement, why in the name of god doesn't this guys take it out of the passenger and throw it out of the elevator? Later in the movie you will see why and even when the director tried to be dramatic in the setting, its just stupid because you will see a thousand ways more easier to take this bomb out than the solution this guys decides to implement.
End minor spoilers...
The first 30 minutes are very well executed but after that, the movie went downhill, horrible last act, only a nice "sentence" in the conclusion and a totally unnecessary stupid dialog to close the movie... this turned a nice possibility in a total low B-grade movie.
The movie does developed in a way that lead you to believe there is something else and there will leave you hanging up until you see the credits and ask yourself what dafuq did I just saw?
It's like the producers/director had to end the movie somehow and screw themselves in the last 30 minutes just for the sake of it.
Really, it's not worth the effort put into the first act, it's not worth the effort period, if you want to see a more intelligent movie about an elevator please go see DEVIL. Even when that movie was fantasy and this a suspense-thriller, the actions and consequences seem a lot more credible there than in this "elevator" nonsense, this in itself is a nice paradox.
4 out of 10 just because of the nice music.
