Despite sharing the same director, it turns out that the connection to Macon County Line is tenuous at best. Other than taking place in the 1950s, and in the same general good ‘ol place (the Louisiana/Georgia state line), this one seems to be called “Return to Macon County“ only because the characters go to Macon County, and then they go there again. It turns out that it’s explicitly not a sequel- even though it’s clearly all to happy to trade on the name.
...perhaps the biggest shortcoming is simply an overstuffed screenplay branching in too many different directions. It’s a far cry from the valiant laser-focus of Guns. Force 10 isn’t a big fat zero, though it’s easy to observe that the Force is not all that strong with this one.
