The first season of Hawaii 5-0 came out this week. This show is not really my thing, but the DVD set is very well done: good quality prints and transfers, and, as a bonus feature, a long making-of documentary originally made for Hawaiian TV.
The impression I get from watching Hawaii 5-0 is that CBS is airing very similar shows today; the network hasn't changed much. It's a Dad type of show, where a stern and grim hero battles against all the annoying people in the world. Like CSI, it's very violent -- the first season has plenty of blood and beatings, people expiring in extreme close-up, that sort of thing. And while it has lots of violence, it has very little sex; it doesn't even have many women in bikinis (unlike the show that took over its Hawaii crew, Magnum P.I.). It's a show for people who want to see justice done as brutally and efficiently as possible. That's not my kind of show, as I said, but it's a decent example of the type.
Here's a scene of McGarrett (Jack Lord) telling off a bunch of hippies and thereby competing with Joe Friday (from the Dragnet revival) for '60s TV's greatest hippie-teller-offer.
