Who writes this stuff? Horrible... (NOTE: SOME MINOR SPOILERS AHEAD) When this movie starts, we find Billy (who claimed at the end of part one never to have been back to the Ozarks) returning from World War II to the home he said he had never been back to in part one when he's telling the story as a much older man. We never find out what became of Billy's parents from part one, as the only characters returning are Grandpa, Billy's sister Sara, and Rainie Pritchard, who has somehow become Billy's best friend. Even though Rainie saved Billy's life during the war (how sappy), the writer's fail to establish any believable friendship between the two young men. There is barely any reference to part one (which has its own problems), and Billy even goes as far as naming his new dogs Old Dan and Little Ann, the names from the dogs in part one. However, the writers in part two make the same mistake as the writer's in part one: they don't spend enough time developing the characters of the dogs to create sympathy for them. This is well done in Wilson Rawls' book (on which these characters are based), but not in the movie versions.
The movie is full of very lame melodramatic scenes, as well, and is very predictable in spots. (The spots that aren't predictable are even worse!) I won't give away things that happen at the end, but these things are so ridiculous that you'll probably watch from morbid curiosity. In fact, some of the movie is so ridiculous that it's probably best to just see it, as it speaks for itself.
In closing, if you like to watch really horrid movies to make fun of them, you'll love this one. If you're one of those people who doesn't like to waste a lot of your time, then leave this one on the shelf of your video store, if they're unfortunate enough to have it.
