Tonight’s best bet is the series finale of the TNT stalwart “Major Crimes ”at 9 p.m. The show, starring

Mary McDonnell ,wasa spinoff of the highly successful “The Closer” and ran for six seasons. If you know what happened earlier this season, you know there’s no chance of “Major Crimes” getting revived, or a reunion episode. Tonight’s finale will no doubt be a tearjerker.
