The game is fantastic and has some genuinly unnerving moments. However, I think the replay value is low. Puzzles are often too obvious, or confusing until you discover a part of the enviroment can be interacted with, but doesn't look like it can be interracted with. This leads to a little frustration when you realise what you need to do. Rather than saying "Ah ha!" it's more an "Are you serious?". The only other thing to mention is a certain boss can be a little annoying to deal with if you die multiple times to it. Having to replay the same sequence ove and over due to easily made mistakes. Non of these problems are deal breakers, and this franchise goes on sale quite often. Worth a play through and is very enjoyable for the most part.
