My wife is watching this, and I've sat in on a couple. I'm struggling with it, and I can't really tell why.
I started watching TAR about 1/2 way through season 11, which aired back in 2007 (it was an "all-star" season, so it's not where I'd recommend anyone to start). One of the more interesting part of the show for me was watching the teams scramble to get the best flights and seeing how they had to scramble when confronted with the choice between a direct flight and one with a tight connection that was scheduled to arrive 15-20 minutes earlier than the direct flight (among lots of other scenarios). Is the next location close enough to walk, or should you get in a cab (with limited $$)? Those were the decisions teams had to make.
If you don't know the background of the current season, it began in late February 2020, and they shut down production because of COVID on February 28, 2020. At that point, two of the original eleven teams had been eliminated. When they restarted, four of the surviving teams could not return for various reasons, so the allowed the two previously eliminated teams to return, so they restarted with seven teams. Because of COVID, they have intentionally kept teams off of public transportation, including commercial flights. As a result, this season is very watered down. Since the restart, the legs have basically been: leave from the pit stop and either take provided private transportation or drive yourself to the first location, do a task, then get to the next location, do another task, and then get to the next pit stop.
It's very must not a typical season, and I can see why it might not grab the attention of someone who isn't already a fan. The best thing about this season so far is that you don't have any really assholes in the cast.
