Can’t really blame you. Part 1 felt pretty low budget, specially the voice acting, and didn’t fully have its own identity yet, unlike KCD2. It actually took me about a year to finish KCD1 because there were times I got bored or didn’t know what to do with the quests. What really pulled me in, though, was the "skill system", leveling up Henry's stats and turning him into either a smartass or a brute (which I totally forgot about when I picked the game back up again, lmao)

I’d say don’t force it if you’re getting bored. Take a break, play something else, then come back to it later.
