'The Walking Dead: Dead City' breathes life into its most satisfying spinoff yet

After a long stretch of pretty weak-to-indifferent spinoffs as AMC has sought to milk life out of "The Walking Dead," "The Walking Dead: Dead City" arguably delivers the most satisfying spinoff yet by combining the signature characters, played by Jeffrey Dean Morgan and Lauren Cohan. Throwing the pair into a zombie-ravaged Big Apple merely adds to the (OK, kind of depressing) fun.
