It's glorious, like an angel's sparklin' loogie.'' I wouldn't borrow that phrase to praise this entire film about redneck Ronnie (Cross), whose ''talent'' for getting arrested attracts a British TV producer (Odenkirk). But then neither would its ''Mr. Show'' stars/writers, who've publicly encouraged even the ravenous not to buy. The story is somewhat stale -- ripping on reality TV is so 2000, when this movie was shot -- but it does boast some genius kitsch (Mandy Patinkin rehearses a tearjerker from ''Ronnie Dobbs: The Musical''). EXTRAS A well-cut trailer makes you think Ronnie could've been an A. A few one-note alternate/deleted scenes remind you why it's just a C+.
