I love Dragnet, every version ever produced. Jack Webb learned his producing skills for this show from the 1950's version he directed and starred in with Ben Alexander. The style was very similar, with the real notable exeption, that Sgt. Friday gets his long monotonous nonologue each episode.
Harry Morgan was also a gem in this show, just prior to his MASH career. His affable, humorous fall guy to Webb's straight man was outstanding and far and away the biggest and best difference between him and Alexander.
My favorite episode was the one with Friday on a panel discussing the pros and cons of drug use. (Friday obviously on the con side) The major proponent was an actor named Don Sturdy, who would go on to become WKRP's drug-addled morning man, Dr. Johnny Fever.... Mr. Howard Hesseman.
This was television that learned from it's prior incarnation, and exceeded the sum of it's parts.
