I completely agree with you, alot of the new games that are supposed to be so good and supposedly have all these amazing new things in them aren't nearly as good as claimed or as good as their zealous fans think.
I was very disappointed by Doom 3 at first, it could have been so good, but after getting over it not being the game I was hoping for I do enjoy it now.
Crysis doesn't come close to Deus Ex or System Shock. Infact I played System Shock 2 more recently than Crysis and enjoyed it more. In case you don't know there's some nice mods for System Shock 2 that enhance the graphics and models, great if you're a fan of it thinking of playing it again.
