On the heels of “Southie Rules,” and in anticipation of VH1’s March series “Wicked Single,” which is bound to be singularly wicked awful, TNT’s “Boston’s Finest” is a welcome sight.

Rather than treating its local subjects with contempt and milking their Boston accents for what is now the most worn-out joke in the country next to the Harlem Shake, the new reality show has only respect for its cast. As the title indicates, this chronicle of a collection of Boston police officers, ranging from gang and fugitive unit officers to beat cops, is meant as a sincere shout-out to law enforcement. “These cops think the darkest corners of their city are worth saving and that they were the ones born to do it,” executive producer Donnie Wahlberg says in the premiere, Wednesday night at 9.
