Even though I liked the 2nd movie, I was a bit worried about the 3rd. The 2nd didn't hold a candle to the original, and it might have been a downhill slope for the series as a whole.
I think it's one of the better films in the series. Dirty Harry is still quite young, and I liked his rookie partner Kate Moore.
The People's Revolutionary Strike Force were a decent set of villains. Though Bobby Maxwell was easily the most memorable of the group.
