I watched The Infernal Machine with three other people. They all liked it a bit more than me, but it's not that they loved it. I wasn't impressed by it at all. The movie is just too long for that kind of story. It could easily have been half an hour lesser long. Slow paced, repetitive, just not really my thing. By the time the mystery was solved I lost all interest in the story, almost fell asleep. As for the acting it's basically all about Guy Pearce, whom isn't a bad actor, but even he couldn't make this movie better. I won't say the movie is a complete failure, as it probably will please other people, but just not me.
