There are a lot of summer olympic sports i just can't get into - like archery, fencing, shot put (and some of the other "field" events)...but then i'm happy as a clam watching rowing (and find it quite riveting) and, no joke, not only look forward to the marathon but can sit on my couch watching the entirety of it without getting up
I'm extremely tolerant of pretty much every winter olympic sport - i honestly can't think of a winter olympic sport that i won't watch/will get bored of.
