i think i gave a 4 to tour/giro, so have to go for 5.
reasons: not enough spice.
AC winning was the only good outcome of the race.
Quintana's abandon was a big down for me.
just one stage actually had a real battle raging on between the contenders. in the rest of the stages, it was more about following others, defensive rides, etc.
If you leave Neimic, the rest of the breaks were bound to win. Neimic's appeared touch and go for a while.
No exceptionally brave ride by anyone.
The only major plus point is that there were far lesser last-km crashes, comparatively.
