Monolith stepping into psycho horror has not worked in their favor. Condemned was awesome, because it was still mostly about atmosphere and tension, but everything else they have done these past years has felt forced and annoying. AvP2 was awesome, but then they had some of the best material around to work with*. Going from Aliens and Predators to scary girl and ghosts, that can't have been easy.
* but watch Gearbox completely miss the point and fuck everything up with their Aliens game.
