Why? I know alot of people who love watching Calgary because they play good offense but play the body all the time and throw some of the biggest hits out there...
I don't see how it's not fun to watch.
Well you're from Calgary, so obviously you'll think that Calgary games are exciting because whether you like the Flames or not, you have some emotional investment in the game.
People can support and follow the most boring hockey teams (and trust me, those teams have lots of fans too), but because they have an emotional investment to them, it doesn't matter if they play exciting or not, but they'll feel excited.
For me (and trying not to be a homer at all here):
Montreal (fast paced, offensive game and exciting younger players)
Calgary (awesome just to watch Iginla, but i've always liked Regehr for some reason too)
Chicago (Kane, Toews... 'nuff said)
Tampa Bay (mostly cuz of Lecavalier)
Washington (Ovechkin, Semin, Green... always seems to be an exciting game)
