With television networks looking for the next big series, AMC is going back to a time-proven focus: Gangster Families. From The Godfather to The Sopranos, everyone loves them — critics and 18-35 year old males who buy things. According to Deadline Hollywood, AMC is developing a series based on the Martin Scorsese gangster classic Goodfellas. The new series is being written by Nicholas Pileggi, the original writer of the film. Good sign, right?
