I cannot say Secretariat seems all that interesting, but a better question I think is, again, it comes down to if you made it a different way, would it have worked better?
If the movie perhaps hadn't been made by Disney (Who produce wholesome family entertainment at the extent of altering history), and say, had Paramount, or Universal Studios, ETC (Who can produce a PG-13 movie with a little more willing to "Grow a Pair" in the context that they'll tell the story with a little more willing accuracy), could it have been a picture to talk about, and not make it seem ironic?
Let's look at the Blind Side, which I'm not going to give a glowing endorsement to either, but say if that had been made by Disney: How much historically would have been embellished to make it a "Disney Movie" and less a "True Story"? Could Disney have made it and have gotten the "Nominated for Academy Award" praise?
Likewise, if Secretariat had been taken by Warner Brothers and was given a PG-13 rating, would have been a story about an Underdog horse with the subplot of a woman trying to do what she does in the picture, could it have been a better movie, knowing what actors would have been kept, what scenes that worked for you, personally, with the inclusion of some PG-13 scenes (or PG, what have you) could you have given it the positive response to it then?
I really won't see Secretariat unless it's something I HAVE to see, and currently, I'm not taking interest in Horse Movies to express concern for, just wanted to see if this "What if?" scenario would have had a different outlook on the picture.
