After watching Jason Beghe play dirty cop Hank Voigt on Chicago Fire last season, I was happily anticipating his spin-off series, Chicago P.D. (CPD). I enjoyed the tension between his character and Matthew Casey, the well-liked firefighter played by Jesse Spencer on the original series. The scenes between the two were always highly charged, and you never knew what either character was going to do. It was the stuff legendary dramatic scenes, and hopefully spin-offs, are made of. But spin-offs don’t always succeed.
