I never saw the original TV series, as I didn't use to watch much telly back then, so I don't know how it compares. The leads in this case are Colin Farrell and Jamie Foxx, both of whom are appealing tough-guy actors. Farrell's love interest is a very interesting woman. The plot is rather James Bond-ish, but presented in this darker urban style, more like the Shield and other modern gritty cop shows.
For me it's a big thing nowadays if a film isn't idiotic, dreary or offensive, and this wasn't. I enjoyed it.
