Review of Rainbow Valley

The plot of this1935 Lone Star John Wayne oater makes no sense to me! Supposedly, the road from ? to Rainbow Valley was washed out by a flash flood, and the local criminal element wants it to remain that way, to aid in their criminal activities, and induce the gold miners to abandon their diggings for the criminals to take over. But, in the beginning ,Wayne rides over the 'trail' from ? to Rainbow Valley, and meets Gabby Hayes, stuck with his primitive car needing radiator water. Wayne empties his canteen and the two resume their journeys to Rainbow Springs, along a wide 'road'. Wayne foils an attack on the auto, and Gabby continues on toward Rainbow Valley, delivering the mail to the P.O. Obviously, the existing road is good enough for an auto to traverse, so what's the problem??!!........Also, things get confusing for me near the end. Supposedly, there is a road work gang ,the criminal gang, and a citizen mob converging on the road work site. But, it looks like the mob confronts the work gang, which looks like it is the criminal gang! The whole bandit gang is blown up as they scramble to get out the way, right to where the dynamite is buried. The head criminal has a fight with Wayne, and somehow accidently pushes the plunger for this dynamite. Wayne then uses the remainder of a dynamite, which he had fenagled from the gang, to finish building the road. See it at YouTube.
