The sizzling Tuesday season premiere of Sons of Anarchy, which drew 5 million viewers, is a tough act to follow, but FX’s veteran firefighter drama Rescue Me put on solid ratings performance for its series finale last night. The closer of the show, which ran for seven seasons, posted 2.3 million viewers, the most for the series since the Season 4 finale. In adults 18-49 (1.3 million), it was the most-watched episode since the Season 5 premiere.
