The most important part of any route in my opinion is this--- will the winner of this route have to be an all rounder? If the answer is yes (and it isn't always yes, hello Tour with only 27K of total ITT), then the route is good enough. Do things like exciting weekend stages, novel new mountain passes, long-grueling mountain stages, scenic passes along the ocean for the TV, etc matter? Of course, but those are all secondary to crafting a fair, well-rounded route. This is perhaps the most fair, most well-rounded route in years so I am pleased with it.
A few personal notes
1) I love finishes like the ones in Longwy, Lausanne, Chatel, Megeve and Mende. Are they the most exciting? No but they're great for people who want to attend the race in person without having to rent a camper and sleep by the side of the road a few days out. In all those case if you've been following the route rumors it's been pretty easy to find a hotel within walking distance (2 hrs or less) of the stage finish while still getting the experience of seeing an uphill finish with the riders coming in to the finale in different groups.
2) I don't miss the downhill finishes, they terrified me and not in a good way.
3) I do miss the South of France, hopefully we'll get a post-pandemic trip to Nice sometime soon.
