UPN's Thursday-night movie franchise seems to be aiming at teen-age boys. Last week it was "I Married a Monster"; this week it's "Thirty Years to Life" (7 tonight on Channel 29), a grim semi-futuristic tale about an adolescent framed for the murder of his dad. As his punishment, he's scientifically aged three decades and becomes a presumably 47-year-old (Robert Hays, above, of "Airplane! " fame). Any more of this poorly written, needlessly violent junk and those "Star Trek" repeats on Channel 38 are going to look awfully enticing.
