shouldve been a Dirty Harry 6 in the late 1990s
around 1998 or 99 - around the time of Absolute Power, True Crime, or even Blood Work in 2002 (maybe instead of one of those -back then he was around the age of Sly/Arnold now and younger than Ford) with Clint directing of course.
The Dead Pool was pretty bad so the series shouldn't have been allowed to go out like that. like the way Stallone did Rocky Balboa/Rambo IV to counteract the series' going out with Rocky V/Rambo III, and the way they did Star Trek VI to make up for V
Clint sort of wrapped up his western genre with Unforgiven but never really did it for the police genre so even more reason to have done Dirty Harry VI.
Obviously it would've had to have been a lot better than the last few DH movies - hopefully itd have been a return to the quality of at least the 2nd film (like Rocky6) with references/call backs to the previous films. a last mission before retirement or pulled out of retirement for something - maybe to do with something that happened in the first films(like Die Hard 3 - another series with a dreadful 5th part) - e.g. a Scorpio copycat or the son of one of the cops he killed in Magnum Force out for revenge against Harry
