The story is a little simple and sentimental, but I didn't have any expectations. I think the cast does a good job with the material that doesn't have enough time to fully flesh out the characters. Eric Stoltz is good too; I never really understood why he didn't get bigger roles. Maybe, his roles will get a second wind when he doesn't look 13. It's a little bit Leave It To Beaver, so is probably popular with the Christian crowd.
I found the movie randomly on Netflix but I clicked on it because I was a kid on Ft. McCoy as well. There were only about 4 kids on the post in 1978, and I do remember a 1950's purity of living there. We lived so far apart we never saw each other except when a jeep picked us up to take us into the schools in Sparta. The POW fences and towers remained, but it was a ghost town except in the summer when reservists showed up to bomb the ranges into oblivion. Years later, after we left, they would turn the barracks, not the compounds into a camp for Cuban "refugees." The movie captured a certain feel to the place that I liked...beautiful woods, Squaw lake, and some old fashioned values that remained on army posts into the 80's at least. It was a fun place to be a kid but the movie only has time to give you a glimpse of that.
