I've actually attended two performances and I enjoyed both.
As with any improvised performance, it's difficult to compare one show to another because they change every time. However, I felt the effort, jokes, and quality were on par between both that I saw.
I also find some of the funniest moments in improvised long form are when mistakes happen as it gives the actors a chance to flex that they take this all seriously but not taking themselves too seriously and their quick wit in how they recover and a couple of my favourite moments were born out of recovering from mistakes (like calling the character a wrong name or forgetting how one character acquired an item). Some of my favourite moments are in the facial expressions of Kelsey and Jenn. When you can illicit a laugh just from how you move an eyebrow or quiver a lip - you have comedy gold. But I loved watching all of them flex their individual talents.
This crew is obviously having fun together which makes it a fun experience for the audience. If you're not into gothic/horror(ish)/darker stuff, you might be more suited to Wit and Whimsy or Tragedy or Triumph, but if you like the gothic style, this is definitely worth checking out.
