Personally,I think Bioshock 2 is great,the hype great, and that the hype WAS justified.
Also,not too long ago I once said SOMEWHERE that I thought Bioshock 1 is better than 2...BUT...honestly...after making a few more playthroughs in Bioshock 2 lately...I'm starting to thinking retracting that statement...because in Bioshock...I feel like I never left Rapture..I feel right at home...and it just feels more awesome every time I play it...and although there is NOTHING like seeing Rapture for the first time in Bioshock 1 when going down in that bathysphere...Bioshock 2 just feels like it come as CLOSE AS POSSIBLE to that same ''WOW

'' feeling
