For less hardcore cycling fans than yourself, the Vuelta isn't always necessarily essential viewing. As a more casual viewer, I certainly took a great interest in it in 2016 and 2017 (mainly because of Contador), but I didn't watch too much of it in the last two editions (though each morning I'd wake up - in Australia - and check out the results); I'm not entirely sure why, as it can certainly produce interesting racing. Maybe I didn't see Yates winning as actually making up for what happened at the Giro, or likewise with Roglic. IMO the Vuelta fields usually end up as good as - if not better - than the Giro, but in many cases they are just names....this isn't their best self. And because it is the third GT (not just on the calendar) for many of us, we probably don't have the same level of hopes and possible expectations for it as we do other races. In that sense I would think that very few Vuelta's would get voted out early in this competition, but at the same time it is unlikely that (m)any of them will be left when only a handful remain.I just like it for the last 50km+ ITT in the Tour tbh. Nah but it had a pretty simple but just solid route.
To be honest I don't think most Vuelta's have been forgettable. I think there's 2018 and maybe 2019, but that's it. 2019 was really good in the 3rd week too with easy mountain stages getting attacks from 2 climbs out and some crazy echelon action as well. Yeah the GC wasn't close but that's the only thing against it really.
Also, the Vuelta basically got really lucky the biggest would-be snorefest of all had Contador retiring and thus taking the piss with agression every single day.
