The whole, "Is that just a Millennial thing?" is easily the most grating thing about the season. I will warn you in advance. It's pretty clear that Jeff Probst is utterly, utterly fascinated with the Millennials as a whole, and he will never shut up about the things he finds different.
I hope you enjoy the season! It's a pretty good one! I was a little grumpy about it at first but it ended up winning me over in the end. I think I prefer last season's Kaoh Rong more, but GenX vs Millennials turned out fine.
