My vote goes to fantastic but I agree with everyone else who voted for fantastically necessary. I'm not sure the "staged" fights have any major impact on the momentum of the game but it gets the fans out of there seats just like a big save or goal and that's a good thing.
Fantastic and these days the art of the hockey fight has lost a lot of its meaning. The passion of 2 players on 2 teams that actually hate each other fighting is probably the most exciting aspect about hockey.
Thanks to Bettman we have no more real rivalries get the so called "staged" fights.
