Let me be the latest reviewer to jump on the bandwagon for Seabiscuit and give it a strong recommendation.
The horse tale where "our horse is too small, our jockey is too big, our trainer is too old, and [the owner] is too stupid to know the difference" is a classic American story about overcoming adversity and the triumph of heart and perseverance over genetics and social status.
There really isn't anything to complain about in this film, the acting was great, the cast was perfect, the scenery was beautiful, and the cinematography and sound were excellent.
I'm sure there will be those who believe that the film is too sappy or possibly even preachy and those who have read the book (which I have not) will undoubtedly have the usual complaints about the book-to-film transition, but this is a great film. As dramas go, it's certainly in the top five so far for this year.
One might even wonder if it has a chance for an Oscar, but being a July release, there's not much hope for that. We'll have to wait and see.
