Brilliant. Especially to be the first of a new IP. Impeccable art direction and environmental storytelling. What locales are more memorable than the drowned hubris of Rapture?

As for single-player FPS combat, I can't think of many superior, except for something more modern like Doom Eternal. Great variety of weapons working in tandem with the excellent Plasmids.

Enemy design is terrifying. The splicers remind me of Reavers from Firefly. Tore themselves to pieces and scrounged what they could to do you next. Inhumane shrieking and banging, lamenting the lost humanity. The Big Daddies and the Little Sisters are a fantastic, dual risk/reward and morality system.

As for complaints, I think the sound design can be overwhelming and abrasive. It's easy for a recording pick-up to be completely washed out by the sound of droning alarms and screeching enemies.

If you've somehow fallen asleep under a rock and never managed to play this one, do yourself a favor before it ages out. I dont think it will any time soon, but you cant afford to miss it. Between the great writing, engaging gameplay, and marvelous setting, you'd have one of the best ever made at your fingertips.
