However, at the end of the last novel he is stabbed by a simple peasant boy with a pitchfork, and dies of the wound (even though two sorceresses are there to heal him). He is hard-pressed against the assassin in the W1 outro, so much so that he is almost bested, and only prevails because of a dirty trick. In the W2, the main antagonist beats him many times. Just a few examples.
So the way I see it, he's not godlike at all. But in this case, he had no real opposition. He's also older and much more experienced, but retains the mutated strength, stamina, and speed. It is also stated in the novels that when he fights, he sees things slow down around him due to the mutation and the potions. These people move in slo-mo for him.
Now, I'm not saying that this vid is not catering for a certain audience as well, but why wouldn't it?
However, in about 2 minutes, it referenced a lot of important Witcher material and touched on key topics (who are the real monsters, what is evil, can it be measured, who has the right to judge) so efficiently that few other trailers manage.
But be it far from me to try to convince you. This is just my opinion.
