it is hard for me to locate the puck during the game (it is a big challenge to my four-eyed vision, especially on TV). Sometimes It looks like people chase something invisible :)). Besides, the field/arena is kinda small compared to football/soccer field/stadium.
I have never tried to play hockey because 1. I am not comfortable with the hockey stick. 2. my ice skating skill is below average. Football & soccer are more suitable for me as I can play the sports with easy-acquired equipment/apparel & I have no problem to run and catch or kick.
Other than that, yeah, ice hockey is an exciting sport.
