I have to challenge people to duels when they make similar comments about Chariots of Fire. Which, I'm not claiming everyone should love or anything. It's just that I work in sports, well, for another month, and the topic of sports films always comes up....and when I tell people that Chariots is easily my favorite sports film of all time, they tell me it sucks cos it's slow. Hey, maybe it does suck, but let's not always equate long or slow with suck, get a fucking attention span.
Raging Bull is my 2nd favorite sports film, though many will say it's not a sports film at all. It's still about a boxer, so it slots into that category.
