Same thing I mentioned few weeks ago. I've completed recently. Bad things are that it's too linear and lacks that mad atmosphere from the first part. There is less focus on vigor/environment combos, and the gears are just there, no explanations. It's all minor to be honest. Now, gameplay is very good, far more open than in its predecessors, and story.... Well, people are exaggerating about the shock element since some parts were very predictable, but still it gave me awesome goosebumps. You know that feeling when you expect something, and are still surprised when it happens. I though about it the whole day(finished last 2 hours in the morning), putting all the pieces together. It's one of the best story-based games out there.
The Lettuce twins, their jokes and behaviour overall were the best. Especially when you find out....
