I never got totally in to it.
I also found the comments in combat annoying and out of place.
It is still a great game, and I'd recommend it to anyone, and I couldn't possibly NOT have played it, but I never found myself totally immersed in it. Maybe it was because of the different vibe, or maybe it was because alot of the game is going through areas that you've been to before.
I suppose at this point I wouldn't sound entirely credible saying its good game. But IT IS a good game. When you compare Prince of Persia games to other games, they are almost as a rule superior. I guess that Warrior Within had a lot to live up to, and it's difficult to look at in isolation.
