Kinda spoils the first film
I'm 3/4 of the way through Magnum Force so far and although i'm enjoying it a lot, I kind of wish it never got made, along with the other sequels.
The first film was all about Harry turning his back on the legal system. He starts to question whether being a cop is right for him and then when he finds out that Scorpio is walking away free and even being given his money, he turns his back on the system and hunts Scorpio down and kills him. Then he throws away his badge, making the decision that being a cop is not for him anymore.
The only reason he's now back as a cop is coz Hollywood can't leave a good thing alone.
I also don't like how the villains are vigilante cops. This is exactly what Harry was in the first film, but now we're supposed to not like vigilante cops and they are seen as villains?
Despite those points, I do think it's a great film.
