A Cry for Help: Sports Movies

I've never really done much sports.  I was always the kid at the other end of the field from where the ball was; picking daisies or daydreaming about being a Goonie and being chased by criminals in an underground cave system. 

Therefore I don't really do sports movies.  That said, I'm looking into writing an article about them so I need your help.  What makes a good sports movie?

I recently saw Rocky for the first time.  Not much boxing but an endearing character and sweet love story.

I also saw Moneyball.  Again, not much baseball; a lot of talking, a lot of maths and statistics but equally as enjoyable as Rocky.

Looking around on the internet shows there is a huge amount of love for Raging Bull, Field of Dreams, Chariots of Fire, The Hustler, Seabiscuit (all films I've yet to see) and many others but there isn't that much agreement on lists of the top sports movies.

Check out a few lists to see what I mean:

Time Out top 50

Top 100

NY Daily News Top 25

I've seen quite a lot of the best sports documentaries; When We Were Kings, Hoop Dreams, Murderball but I still need to see Senna.  What are the best documentaries about sports in your opinion?

And how come a film like Point Break isn't classified as a sports movie?  There's a hell of a lot of surfing and skydiving. 

What about future sports; do Rollerball and even something like The Running Man count?

Do you have to like a sport to like the film about the sport?

What sports make the best films?

Are documentaries about sport better than fiction films?  What are your favourite sports movies?  What should I see before I go any further in life?
