It's a long boring movie with a few moments of excitement. About the only good thing I can say is it's locations look better because unlike most movies back then it wasn't filmed in California, it being filmed in the South makes it look way better for a CW movie. But I imagine everyone who has seen a CW movie from back then has seen footage from it, the battle footage from Raintree County was used in another movie or two, the main one I can think of is Shenandoah, with the battle scenes in the beginning being the same battle footage from Raintree County.
I've read somewhere that Raintree County was intended as a Northern version of Gone with the Wind, and some aspects of the movie seem to confirm it to me, but I'd say the result was a far cry for movie going audiences. One funny thing about it is Montgomery Clift, he was an alcoholic at the time, and through some series of unfortunate events he had a wreck during filming that disfigured one side of his face thus making them have to only film where the wound couldn't be seen, and to top it all off his medications supposedly made him "fall of the wagon". For example he supposedly went screaming off the set or his hotel room, (I can't remember which) and was found running around a nearby by town butt naked. After that police were kept around him for the remainder of filming to keep him from running wild again.
The movie is little remembered today, and I'm willing to bet the stars of the movie wanted to keep it that way, but it did get top marks for sound.
