I enjoyed it too. Tho maybe it isn’t finished properly. The quest I mean. I was meant to talk to the prior about certain things that a certain monk asked me to do but the game never gave me the talk option about these things 
I despise the monastery. It was the only quest I absoloutley HATED in this game. After I finished the game I saved just in case, then went into the monastery at night and killed as many monks as I could. It was satisfying, until the guards came xD
It’s one of the best quests in game. It isn’t compulsory become the monk for finish this quest - it might be finished in one night.
