It's good so far. Combat is rather basic but enjoyable, very stamina focused, the world is interesting to explore and good looking (heavy dark fantasy themes here) for a AA game (don't expect KCD 2 here) and the story has got a nice hook. It remains to be seen if all that holds true after 30-40 hours but so far I'm enjoying it.
Controls work right out of the box, the graphical update in 1 is great and keeps the atmosphere of the original intact. Most importantly you can switch between the two versions. Bonus cut content is available for those who want a glimpse on waht was cut.
