Finished F.E.A.R. 2 two days ago. Loved it. Despite some flaws, It's an enjoyable, fun and beautiful game.
This is a game in which I can see some flaws, but, regardless, It just fit me. Sometimes it can be repetitive, specially the chapters that are played in abandoned office buildings. Also, there is not much variety of enemies you can fight. You can perceive that the game doesn't reach its full potential.
But, despite the above, the mix of a solid shooter with a supernatural horror story is just great. The settings are beautiful and detailed, the sounds and the music are superb, the action is fast and intense, and the encounters with Alma are scary.
The story, also, is great. Piece by piece, you begin to discover what's about Armacham Corp. and it's unnatural military projects, which involved experimentation with clones (replicas) soldiers and the exploitation of a little girl with enormous psychic powers. Te pieces of information you get trough the game are just clues, so it's up to you to figure it out what's really happening. If something isn't totally clear, you can always go to http://fear.wikia.com and read the details.
So, in the end, you have an enjoyable, fun and beautiful game.
