The Enforcer
A great buy for DVD format. Loaded with plenty of background on filming, story, and cast/crew. A top-notch production for a great movie series.

The Best of the Dirty Harry Series!
It has all the other things you expect from Harry Calahan and more humor too (that sequence with the mayors assistant and Harry and Tyne was very very funny!)

Cleaner Still
Third Dirty Harry picture feels more dated than the previous two with its portrait of crazed radicals as the bad guys none of whom register as believable or menacing villains. The picture feels more like a violent TV episode from the era. Like in Magnum Force, Harry is made into more of a conventional cop hero than the extreme personality from the first (and far and away best) film. The whole show here is his relationship with Tyne Daly as his partner. These scenes are the best in the movie and both actors deliver.

Middlin' Eastwood in nice Deluxe Edition, details here
The Enforcer is the second sequel to Dirty Harry. In this installment, Harry Callahan, the renegade cop with some old-fashioned attitudes and no desire to be tied up with a partner, gets stuck with a female partner, well played by Tyne Daly. Surprise surprise, he learns to respect and rely on her as they make hamburger of a group of domestic terrorists. As in the first two movies, there's plenty of action, suspense, people getting shot, etc., but with a chase on foot in place of the usual car chase.

Whether those with the older DVD will want to upgrade is a matter of personal preference, but the special features look attractive to me:

-- new commentary by Enforcer director James Fargo
-- new featurette "The Business End: Violence in Cinema"
-- "Harry Callahan/Clint Eastwood: Something Special in Films"
-- trailer gallery

This and the other four movies are available on standard DVD both separately and in a 7-disc Ultimate Collector's Edition, which has additional goodies.

They're also on Blu-ray in a 5-disc Ultimate Collector's Edition. Only the Dirty Harry Special Edition is available separately on Blu-ray (here); the other four movies, including this one, are available on Blu-ray in the set.

Here are the links for the Amazon pages for the new separate standard DVD releases of the other four movies in the series:

Dirty Harry Special Edition (2 discs, "special" is apparently better than "deluxe")
Magnum Force Deluxe Edition
Sudden Impact Deluxe Edition
The Dead Pool Deluxe Edition

Worst of Three Detective Callahan Flicks
I know there are 5 films with Clint Eastwood playing the "Dirty Harry" role,but because of the time between the third and fourth installment and the commercialization of the franchise, I only really look at the three Dirty Harry films from the 70's as part of the series.

I don't need a complexed plot to enjoy a Dirty Harry film. Clint Eastwood acts fine in California based cop flicks with little dialogue as he did in his great Westerns during the 60's. There is decent shot-popping action in "The Enforcer" as Callahan and it is surely a watchable and not boring film.

If you are looking for a continuation of the Cop vs. Bureaucracy tale that made the original "Dirty Harry" so compelling, you may come away unsatisfied as "The Enforcer" tacitly embraces some of the PC stupidity so cleverly attacked in the first go-around. It's a bad move for the franchise and the world introducing future "Cagney and Lacey" star Tyne Dailey as Harry's quota-hire female partner. Subtle message here is one of "gender equality" and shows Callhan developing deep respect for the lady cop he was reluctant to work with. Maybe Eastwood wanted to do something he hadn't done in the first two Harry flicks and show some sensitivity and maybe even deflect some of the media criticism of his macho and rule bending character.There's not that much of the PC nonsense, but enough to make one wish they took a script another way.Preach in church, not in action movies..
Good villians help me forgive the PC pandering undertone. Lunatic leftist revolutionaries styled after Patty Hearst kidnappers the Symbionese Liberation Army are the culprit here, with a full-70's ambition of helping the poor fight "the man" and "off the pigs". Nice appearance by Robert Mitchum brother John as a fellow lawman.
