Panic Button, a British indie horror movie that got several quite good reviews and a few great ones. There are so, so many things about the movie that are awful. The awkwardness of the key metaphor, the contrived and bizarre way the characters act (I think the actual acting was fine for most of the actors, but the writing was so bad I couldn't really tell), the same-ness of the scenery throughout the whole film, the predictability... it was all awful. The absolute worst thing, though, was the pacing. See, there are many, many points in the film where each of the 4 main characters interact with a 5th character. And the first of these exchanges establishes EXACTLY what's going on. And then they do it again for the second character, adding nothing. And then the third, adding nothing. And then the fourth, adding nothing.
And then we do it all again.
I've never been so bored in a film in my life.
