I disagree. The game was absolutely fantastic. It was never about problem solving or challenging my brain etc. It was about creating an incredible experience through the atmosphere, music and graphics (along with the back-story and intrigue). The moment I stepped off the train I got chills down my spine with the music and the deserted train station, with the voice of authority booming down. The super aggressive guards, the scared/confused people, the desolate streets, the whole thing was perfect to a point. There were sections which were forced or not interesting (using the pheromones for example), but I can't remember other games where I had that "wow" moment so many times. In fairness I haven't played many games for the last few years (including Portal), so maybe there are other games which have improved upon that. But at the time it was amazing.
