Again, people on here said the show was on its last legs when it switched to the Friday timeslot. And then again for Sundays.
TAR has always, for what it is, come in at reasonable cost. Prize money aside, most viewers might be surprised that The Traitors, while being set at one location, likely has higher costs simply for celebrity signing rates. As to how expensive the show is and whether or not it stays on budget, again, literally none of us know. If it's managed this far AND not gone down to TARCAN levels of product placement, it seems, to me, like a non-starter.
I would much sooner believe that the show becomes untenable due to sociopolitical issues than the other reasons because, quite frankly, all the other reasons come out of the woodwork every season because people don't like the route or the teams or the boot order or the timeslot or the shift to only-spring or only-fall schedules or delayed casting or yada yada. It's the same argument we see for TARAUS every year too. The shows never do enough for the small number of ardent fans on RFF, and that always seems to be the bellwether for some reason...even though it's never been correct thus far.
