I loved this show, but it is never okay to trick people into believing they're watching a comedy and then bombarding them with a story about grief. As someone whose parents are both dead when the show ended, I broke down to the point of having to call a friend to take me home instead of taking the bus. This is a good show, the actors do such a wonderful job of portraying different ways of handling grief and how we try to move on, and don’t get me wrong it is hilarious. I understand why they don’t have death or grief (both apply for different reasons) in the content warnings as they use it as a plot point, but if your show can be ruined by people being aware of triggering content then you are doing something wrong! And I don’t believe the show would be ruined if they warned people, as I was able to guess the ending after the first 5 or so minutes and it still broke me.
I used boss quiet comfort headphones and a tangle, I should have also used sunglasses as they have an uncovered light bulb as a prop on stage (it does work very well, but it is bright). There is also a backing track during the "intermissions" that is both thematic and annoying, headphones definitely help.
It surprises me that a show that seems to truly understand grief is so negligent of the feelings of the people it represents. With the way they represent this show, I would not recommend it, but with a couple of changes to their description and some more content warnings I would.
