Based on a true story.
Low bugdet? Um, it's a made-for-TV movie and two-thirds of it is set in the 60s.
Bullying dad? Possibly, but real life for many who grew up in the 60s had this type of family dynamic.
Christian undertones? Well, they visit with a military chaplin a few times - if you believe we should all coexist & celebrate each other's differences, then it shouldn't be a problem.
Inconsistencies? Yes, some, but when have you seen a TV movie without any - never.
Overall: good, heartfelt, love always prevails movie
