I also thought it was a fantastic "feel good" movie. I went with 3 out 4 of my kids (including my 2 boys that are 5 and 7). I thought it would be to slow for them but they genuinely liked it.
Caddyshack aside, this is The Greatest Golf Movie Ever Produced. As a golf history nerd, I found only three minor mistakes (Vardon was missing his tademark mustache, the actor playing Johnny McDermott had one, and Ouimet won by five shots, not one on the last hole).
Entertaining, well written (The book won the USGA Book Award the year before last), funny, touching. I give it two thumbs up.
