Think of Kingpin as ''El Godfather.'' It's violent. It's chillingly intense. And it's oh-so-addictive. NBC's gripping six-part miniseries (which originally aired in February) centers on Mexican-American Miguel Cadena (a masterful Yancey Arias), who takes over his family's drug empire. But considering he's married to a manipulative cokehead (Sheryl Lee), fears his bloodthirsty brother (Bobby Cannavale), and has those DEA agents on his tail, Cadena doesn't need his Stanford degree to see that a drug lord's life is hardly material for a Norman Rockwell painting. EXTRAS The cast interviews are a 20-minute snoozefest. And if trailers are your thing, you won't find ''Kingpin'''s -- only a shameless plug for NBC's ''Law & Order.''
