The first 30 or so mins of this film are classic Dirty Harry, plenty of action and some brilliant lines. Unfortunately the film slows down later on, with too many slow and sensitive bits for my liking. Please don't misunderstand me, I am not looking for mindless action in a film, I just mean that Clint (who directed this film) tries a bit too hard to inject meaning into the actions of Sandra Locke (his co-star and girlfriend).
Overall it is an enjoyable film with some outstanding one liners from Clint, though I admit I did press the fast forward button a few times in the second half.
The blu ray transfer is sharp, with some scenes looking like they were done today. However, some of the camera work is a bit blurry and out of focus. I would say a definite improvement over the DVD and definitely worth getting if you don't have it on DVD already. The sound is offered in 2.0, 5.1 and also 5.1 Dolby TrueHD. I used the TrueHD sound and found it good (although bizarrely quieter than the 5.1 track, I had to crank up the volume on my amp).
