To be honest, I never really liked spectating any sports. I did watch WTCC and FIA World Endurance Championship for like one season respectively, and as a kid I enjoyed watching WRC and snooker, but that's pretty much it. Oh, and obligatory world football cups when Croatia would play, but I don't count that for this purpose. Heck, I don't even remember if I ever watched a full race of F1.
I just don't find spectating sports, at least on a screen, particularly interesting. Granted, my attention span is not the greatest when it comes to this sort of stuff, but there's also an element of interest which I just lack, and to be quite honest, when it becomes a kind of obesssion, don't understand. I can understand people marathon-watching stuff like their favourite TV shows or movie series, but this is just too repetitive from my point of view.
My mum and brother and very much into watching cycling, and they watch every single race, they would even watch reruns of old races (i.e. before they really got into cycling), and I just don't understand how don't they get bored of it. I get that one can spectate a sport occasionally, but to watch every single race obsessively?
Then again, whenever I get into a TV show, I watch it episode-by-episode, in sequential order, to the point when I get bored with it.
