You never really know what you’re getting into when you try a new TV series. It’s like a blind date; you hear the positive spin, get the stink-eye from your sparsely-populated social calendar, review your “nightmare scenario” contingency plan and decide to give it a shot. That’s how I found “Terriers”, and it was love at first sight. Smart, genuinely interesting and wryly funny, “Terriers” treats its viewers as adults and showcases the phenomenal talent of its cast and crew every single week, never faltering in its quality or its humanity. Others have made comparisons to “The Rockford Files” and I don’t disagree with that, but I’d widen the scope farther in terms of the maturity of its writing. I grew up in the ’70s; when I rewatch some of the shows from that era, the two things that stand out most are the sophistication of the dialogue and the maturity of the storytelling. “Terriers” offers both of these things in spades and carries the extra distinction of a gifted cast. It’s become “appointment television” for me, and that’s a phrase I’ve used a grand total of four times in my life. So I’ll be at our usual table next Wednesday, “Terriers”, with a smile on my face and a willingness to follow you anywhere.
