Score: ◆◆◆⬖◇ (3.5/5)
This is a decent quest DLC that could perhaps have been a bit longer, but you are essentially aiding Sir Hans with wooing the "love of his life" which turns out to be much more complicated than you'd think.
I think some of the negative reviews for this stem from the fact that you can completely skip the 3rd quest of the DLC by simply buying the potion recipe and while normally I applaud KCD for giving you options in how you complete a task, this might have been a mistake to include since this 3rd quest is the most fun, as well as the longest of the 3 quests in the DLC.
Skipping this quest means completing the DLC in a fraction of the time and missing out on helping a charlatan trick an entire village into thinking its haunted. If you choose to grab this DLC, I highly recommend you complete the quest without buying or pickpocketing the recipe from the charlatan.
