We watched the first episode and like the teams so far. No one really stands out as over the top annoying, though the sisters to which you refer are dancing close to the line. I didn’t quite understand what they were talking about, so that might have helped.
I noticed a lot of sibling teams this season.
I liked that the leg had tasks that were random enough and/or difficult enough to allow significant position changes at each one. I find FIFO tasks incredibly boring unless the location is exceedingly spectacular to justify a non-meaningful task.
We have been watching old seasons of The Amazing Race to ‘travel’ during these no-travel times. Having a new race right now is pretty cool, except since this is the One Million Miles benchmark, they showed clips from past shows that are spoilers to us (not that I have a right to complain, these are many years old spoilers).
Our absolute favorite thing is when they visit a place we have been, so I’m hoping they go somewhere we know this season.
