I Felt Pretty Overwhelmed With Mechanics, And Not In The Way Visits To Ravnica Usually Are Since They

I felt pretty overwhelmed with mechanics, and not in the way visits to Ravnica usually are since they weren't matched with the Guilds and each mechanic felt more complex than the Guild-specific ones even if it wasn't necessarily. Disguise, Cloak, Suspect, Collect Evidence, Cases, all combined with the return of Investigate and a few other keywords. I'm all for Ravnica expanding from the ties of the Guilds as mechanical constraints, I liked War Of The Spark and it kind of broke away from those rules, but this much at once felt like a whole new plane grafted onto Ravnica, something I know is partially true since the set was meant to be on a new original plane before they decided it was "stepping on Ravnica's toes."

I've seen lots of people say that MKM failed, or that it wasn't popular. Maybe that it failed to capture the feel that people expected.

I personally liked the set, so I don't know why people say this. Do you know what is that people disliked?

Let’s ask. For those of you that didn’t like Murders at Karlov Manor, what didn’t you like?
