I saw them as an opener, they were alright. Their set was an hour long and they took almost 40 minutes to set up, which wasn't great but I get stuff happens, there might've just been some weird issues.
I'm admittedly not a huge fan of their music but it wasn't unenjoyable. A good like half of the crowd was moving and seemed to be enjoying them.
Then after one of their songs the lead singer immediately started yelling at someone in the crowd for not paying attention, and demanded they leave. It was super uncomfortable, people were looking around super surprised and after that I've never seen a more dead crowd, it *really* killed the vibe.
