When you say you're being spotted, do you mean the yellow circle alert or the red attack one? The yellow one could be caused by AI patrols finding the bodies of your victims.
I've completed the game on Marksman difficulty level and I don't remember seeing any random AI spotting behavior, but maybe I just got lucky.
Anyway, I've been enjoying the game although I can see how it's not for everyone. There is quite a lot more sneaking around getting stealth kills than I expected. I'm finding it quite reminiscent of the old Hidden and Dangerous games, in a good way. The 7-8/10 review scores it's been getting seem fair to me.
