Lords of Shadow isn't a castlevania game. Think God of War... If you haven't played Castlevania for the last 20 years and have no expectations and don't mind the fact they threw out everything that makes Castlevania awesome...you may enjoy Lords of shadow.
Just be aware, the game is repetitive, unoriginal, has really annoying static camera and has one of the most boring and depressing stories you'll see in a videogame. Looks great though...
Enslaved I rented and I got bored with it in 2 hours hence I returned it so I can't provide a worthwile opinion.
Vanquish has a pretty terrible story as well, but it knows it and has fun with it. It however rapes both of those hack and slash games sideways in terms gameplay, and if you want to "play" your games, I highly recommend Vanquish. The upside down monorail sequence in Vanqish which lasts for 3 minutes is more fun than anything you'll find in castlevania or enslaved and their super long gameplay glory. And no pattrick stewart narration was needed...
