Badminton for sure !
Mixted doubled are very entertaining
Only Womens double are boring (lesss boring than any ping pong or tennis double tho )
figure skating ( if winter olympics count )
skateboard, if the male was cool to watch, imagine the female
probably beach volleyball, discus throw, javelin throw and hammer throw which I will just watch because of Olympics. love tennis the most out of those generic sports
volleyball is super cool to watch, especially mens they hit very hard mens))
Tennis but I love it outside of the olympics.
