KCD is unique, personally I love it. In some ways it's kind of the dark souls of first person RPG. The systems are at times a bit clunky, combat is hard, complex, and both you and your character need a lot of training to be profficient.
But that's the fun of the game. Henry is a useless lump at the start, and you mold him in to what you want.
Personally, I love hardcore challenging single player games, and few in recent years match KCD.
I dont have a system to play KCD2 yet, but from everything I've seen, the developer doubled down and kept the majority of the systems in place, just adding scale and polish.
I'm sure the first one is on discount these days, and highly recommend it.
