While The Happening is a truly awful movie on every level, Only Shyamalan's version of Avatar:The last Airbender can rival this one in terms of sheer awfulness. The writing is abysmal, the plot is novel, but ultimately just a simple idea spread out across too much screen time. The characters are absolutely nonsensical; they just exist on the "old" beach for the entire movie, knowing that they will die if they stay, but never really making a concerted effort to leave.
This is another example of Shyamalan attempting to shove a "twist" into his movies, when this one is obvious by about the 20 minute mark. He attempts to jam so much exposition into the dialogue in an attempt to be absolutely sure that the viewer didn't miss something, the writing comes across as absolutely unnatural. People don't talk like this. He attempts to have the characters explain how they are qualified to jump to certain conclusions about what is happening to them that it just seems amateur, like a low quality fanfic instead of a full release movie. I don't understand how this made it through so many filters without someone saying "Hey, maybe lets make a second draft before we publish"
I could spend a lot of time breaking down how dumb this movie is, but I'll just leave it there. Don't waste your money on this. At least The Happening was fun to laugh at. Old is just infuriatingly bad.
