Amnesia: Rebirth isn't a bad game, but it doesn't live up to the series for which it's titled. While billed as a direct sequel to The Dark Descent, it feels further removed from that than the indirect chapter, A Machine for Pigs.
It's got some nice monster designs, and it's a decent enough horror game, but it fails to stand out amongst the sea of scary games that landed in the ten years since The Dark Descent influenced a genre.
