I have a British friend who has lived here in the US for about five years. She is actually a published top of the field researcher in genetics. The first few times you would meet her socially, she would fill quite a bit of space with an entire, and initially pretty funny, litany of why living in the UK sucks, why the British are idiots easily swayed by promises of "free" goodies from the government. About how it is a nanny state, about how people there have given away liberty, about her sister in the UK waiting a year to get treatment for a condition that is easier to treat the US, and about how being in the EU has given control of so many aspects of UK life to un-elected bureaucrats in Brussels. At first it is pretty funny. Couple of fairly funny anecdotes. But at a certain point it becomes repetitive and you kinda get ticked off that the gal endlessly is slamming her country to people from other countries simply boosting herself socially, trying to fit in, by spewing nastiness about her own country.
Watching Jackie, Rob Delaney is exactly this kind of person. A one hour shtick in that vein is just interminable and you will find yourself eye rolling after about ten minutes as this standup turns into one long idiotic rant.
Rob Delaney's "Catastrophe" sitcom ran four seasons. The first season was pretty good, and then it fell into a repetitive rut and was cancelled as ratings fell and fell. If you have seen first season of catastrope, you can skip this and be glad you did.
