How bad is it? It's exploitation, but it's a fairly solid western.
Should you see it? Yes.
This is actually one of the better films directed by Sam Newfield, a standard B western with fights, shoot-outs, chases and even two songs. It just happens to have "an all-midget cast." Once you get past the scale issues, it's a decent film. The plot has an evil cowboy threatening a town and getting vanquished. Star Billy Curtis acted in another western 35 years later, "High Plains Drifter," with Clint Eastwood and availed himself well there, too.
