I don't do movie reviews so this won't be elaborate, eloquent or particularly moving, I just want to strongly suggest to everyone I possibly can to save your $10 and see... anything else.
If you want the short version of my review: I didn't know whether to laugh or cry at how bad it was.
I honestly don't throw this category around blithely, but this was easily one of the worst films I have ever seen. The only thing interesting about it was how it actually managed to be awful in basically every possible way.
One more thing before I dive in: I'm not a Shyamalan hater. Aside from Signs I've enjoyed all of his movies... yes, even The Lady in the Water. My favorite is Unbreakable.
Now, on to the schlock:
Acting
Overall it was amazingly bad. Mark Wahlberg was decent in some moments and very poor in others. Apparently he thinks talking in hushed, wispy tones = being sensitive. Leguizamo... okay, actually I enjoyed him for nearly half of the time he was on camera. He was more held back by the corny and vapid dialogue than anything. Zooey Deschanel was a joke. I hesitated to even put her performance under "acting." The 11 year old co-star had more depth and believability.
Dialogue
Far from believable. It was shallow and imbecilic. The only time it got 'deep' was when everyone was in a panic and racing for their lives... when it should have been shallow and imbecilic.
My favorite part of the dialogue, though, was the delivery. Ever watch SNL when they are making fun of bad acting? One of the easiest tools is to add awkward pauses mid-sentence as if the actor has either forgotten the line or never understood what it actually meant. This happens about six times in the movie...
Direction
Not sure where to put this elsewhere, but the flow, the responses to specific events and situations were an absolute joke. Spoiler-ish: The idea is that the toxin is airborne. So... if someone yells to tell you that you need to close the windows and doors because it is coming, what would be your response? Close the windows and doors, right? Not so in the movie... instead we like to look longingly at our death blowing over the grass so that at the very last second we close the window. "Tension" created out of stupidity.
The Sensationalism (minor spoilers)
Part of the event is that people effectively become suicidal. What's cheesy is that not only are they suicidal, but they also seem to intentionally seek out the most fantastic and graphic way to off themselves. If you're trying to show gory and implausible ways people can commit suicide then make a Faces of Death film. In this movie, people walk past 15 ways to kill themselves simply to set up an elaborate scheme so that it will look cool.
The Happening/the Twist (spoilers in white)
While exaggerated, some of the science actually makes sense. And thus ends the decent twist. What is apparently overlooked - either by Shyamalan or, he hopes, by the viewer - is that the wind is apparently involved. It isn't the plants that chase people, it is the wind. So either the plants are talking to the wind or making the wind. Neither even comes close to making any sense whatsoever, so even the premise of the whole ordeal is pathetic. And that's not even including the made up statistic of "the crest" that eventually saves the day.
And then there is the inconsistency of infection. Throughout the entire movie, groups of people standing next to one another are affected immediately with only two exceptions. Fortunately, those two exceptions (immediately at the beginning and ending of the movie) are willing to provide us with 'coherent' dialogue about those around them, particularly their friend at their side. How convenient.
Blah blah blah... aside from that the soundtrack was tacky and overdone, seemingly every minor character was such a caricature or buffoon that you prayed they never met anyone else, almost no one acted as anyone actually would in a crisis, and the wording of what was going on as "the happening" to keep tying in the movie with the title was so contrived that it made me squirm in my seat much more than any of the senseless gore. And I'm only stopping because this is too long already, not because there isn't more awful to warn you about.
Okay, I'm done rambling. Don't go. You'll thank me.
