Do what you like with your free time and don't worry what others do with there's.
I used to watch a decent amount of Olympic stuff when I was younger, but haven't watched much the past two times. Mainly just due to being busier. I do enjoy track and swimming, as well as sports I watch regularly like basketball and soccer etc. and there's some novelty to watching random sorts like fencing in small bursts.
I guess it really just comes down to whether you're interested in sports and athletic competitor or not. If you are then there are going to be at least some events that appeal to you. If not then the whole thing will be a waste to you.
The TV coverage on anbc jumps around too much. But there's more consistent coverage on their cable channelsif you have cable/satellite--Bravo, CNBC and MSNBC, as well as dedicated basketball and soccer channels.
