OH YES. Time for me to rant.
There is a trend that I've noticed in later seasons, which is the legs staying in one city -- ESPECIALLY this season. That makes for quite a bit of lost taxi situations, which I dislike. Compare TAR 5 with a whopping 31 cities to TAR 13 with only 18. (Looking at this season, we may end up with only 10-15 cities.)
What happened to the legs in which we traveled through the country and ended up in some place in the countryside? Take for example, TAR 14 Switzerland and TAR 13 Cambodia. We visited a whole bunch of cultural landmarks, traveled away from the city and took in some of the culture not usually thought of as being related to that country.
Unfortunately, I find that there is no one perfect TAR season. Most often, the season fizzles out towards the end, since I'm always feel odd about a certain team having a lot of screen time (That's why I say 6-8 teams make for the best episodes). From what I've watched about Season 9-15:
Season 9-11: The endings were all ruined because the teams ended up at their final destination midway through the episode, thus leaving them to only do one task at the final destination.
Season 9: An excellent race route with generally competitive teams. (What's so bad about this season? Alpha males were entertaining.) I shall compare the Tokyo leg of this and that season. Although TAR 9's visit to Tokyo was marred by an overnight stop at the capsule hotel, we did see not only the bustling city of Tokyo, but also the countryside. Compare that to an odd Japanese game show and herding tourists through Shibuya, where we've already been. You could remove this episode and I wouldn't care. This year's premiere would have been much better if they started with a double-length Vietman leg.
Season 10: The style was like Season 9, except the teams were like those from TAR 14 (more on that later). Dustin and Candace are the most competent FF racers I've seen on the Race. We got the horrid intersection (lucky it was removed after All-Stars). Once again, flights from Paris to NY ruined the last half of the episode.
Season 11: Too much time in South America! Otherwise, it wasn't too bad. Some old favorites brought their magic back. Worst TAR finish ever.
After Season 12, TPTB fixed the problem of the multi-area final legs. I don't have to see so much Alaska/Hawaii again! Then, we got the LA starts, the decline in tasks, and questionable casting (which has improved lately).
Season 12: This season gets a lot of flak for its bland cast and tasks. Still, I like this season better than 13/14/15. There were a few gems, as the boring team were eliminated quickly. Goths + Asian Family + Grandad = Awesome. Nate and Jen were good villains too. We had 5 new countries to visit, which is always good. I liked this season's finale (though I disagree with the winners), since I felt they actually went places and raced.
Season 13: The general route was pretty nice. There were a few gems in there, such as the Cambodia leg. In contrast to Phnom Penh this season, it felt like we saw a lot of the country (Tonle Sap and Angkor Wat). Boat-riding was fun! However, this season had terrible teams that I could care less about. Nick and Starr were too strong, and that took away a lot of the drama. And don't get started on Dandrew...
Season 14: At first, it seemed as if the race was revitalizing. The Europe legs did go places and had relatively interesting tasks (even though they're somewhat stereotypical, at least they were slightly challenging). Then, we got hit by boring Asia legs, especially after Mike and Mel left. There were some bright teams that brought quite a bit of action (it's your opinion whether it detraced from the show). The TAR 14 finale wasn't half-bad either, though I've grown tired of Hawaii. Why not Canada?
Season 15: Oh dear. Teams are slightly above those from Season 12/13, but the tasks! Despite the "indirect clues," I have not been intrigued by any of the detours so far. I would say only the duck task was fascinating so far.
For a change, why not have the race immediately start in the first country visited (and end on the East Coast/Canada)? This gets rid of the obligatory flight drama at the beginning of the season. Less blatant bunching as well please! Signs of improvement will include the countryside and boats/buses/trains/self-driving instead of cars/planes.
