It’s exciting to see Shyamalan on such confident footing once more, all these years later.
"Support Your Local Sheriff" is a textbook example of the evil influence TV has on the movies. It's essentially a lousy TV situation comedy dragged out to feature length for no good reason.
It has all the hallmarks of a TV half-hour: the overdone background music (to tell us what's funny), the self consciously arch lines, the cheap production values, the weary puns ("Let's go down to Madame Orr's house.")
The idea, I guess, was to parody the traditional Western. That is a good and noble aim; recent successes like "Cat Ballou" and "El Dorado" come to mind. But those two films had a life and freshness of their own.
"Support Your Local Sheriff" is not a parody but a theft. It depends on our own buried memories of countless other Westerns. It has no steam of its own.
