SHAMELESS
Showtime, 9:00 p.m. ET
Last week’s “best of” special look back was all about Fiona – played by Emmy Rossum, who departed the show last year. Tonight’s is about the paternal central character of the show, Frank Gallagher, the singularly unpredictable and usually unreliable patriarch played so brilliantly, for so long now, by William H. Macy.
