The story and the world world have quality, they did put much attention there, but the rest is sadly sub standard or simply broken.
I disagree. It took some time to get used to but after few hours I think controls and menus are quite good. Not perfect, but much better than most Capcom or Koami titles (Resident Evil brrr).
There are plenty things you can do in Witcher on instant - fight with two kind of swords (fast or strong attack), fist fight, throw bombs, shoot crossbow, cast signs, block, parry, roll, sidestep, jump, climb, run, call horse, target enemies, use witcher senses and that makes controls slightly more complicated than usual, but it's you who decide what witcher will do. There is a diffrence between Witcher and for example Assassin Creed which has "simplified" gameplay, where tapping the same button will give plenty of diffrent outcomes, depends on situation, but in fact the game offers you automated gameplay. In Witcher you have to push proper button yourself or you will fail - the game won't decide for you.
I admit I had some troubles with jerky movement of our hero, but I tweaked camera sensitivity to 0,7 of initial value and it's great.
