It's mindless, it's vacuous, it's vapid. The story is crap, the characters are crap, the lore is pissed upon.
But it's the most fun I've had playing a game in a long while, so who cares. Killing orcs, storming forts, avenging deaths, scaling towers, collecting stupid collectables, I can't stop doing it. I haven't paid more than "50% off" for a game in a decade. Bought the super mega-restore-the-cut content edition from GMG for $80 soon after launch in an urge to spend money. Instant regret for the first few hours, but then I got into the meat and flow of the game, and now zero regrets. It will be super cheap in a year, and probably a GOTY in two years. If you didn't buy it yet, it will be a must-buy at <$20.
I am using Cheat Engine to modify FOV, though, and that has added to my enjoyment immensely.
