Let's first dispell a myth..
Please, do not read anything into the animal rights activists scaring people into not buying this film. 'Clyde' or 'Clyde 2' which was involved in the 'Any which way you can' film, died from a cerebral hemorrhage, which had nothing to do with the treatment of the orangutans well-being. It was properly cared for and treated well all of its life. As was the first 'Clyde' an orangutan called Manis, who lived to an old age.
As for both films.. Clint Eastwood just instinctively knows when something is right to do. Despite being told not to make the original film, he made it anyway and it was a hit. The public love Clint Eastwood and they also like the movies despite the negative press around the films at that time.
Clyde is the great comedy sidekick and bit of an unknown quantity, if you watch the films for the first time, you never knew what you were going to get. There's lots of funny moments and it's a comedy at heart. However, it still retains the macho theme, with Clint playing a bare-knuckles fighter to bring in some extra cash when he's not carrying car engines around the backyard.
The highs and lows of relationships between Eastwood and Locke go full circle in both films. There's lots of tongue-in-cheek humour and mild swearing by todays standards, however, don't buy this for kids under 15 years and then complain about all the blood - the certificate is there for a reason, and this is why it's still rated at 15.
The country music sets the tone for the film and is very much in-line with Eastwoods style of film-making and the characters and the locations. The 'Black Widows' make the film even more entertaining and the soundtrack is well-written as you know when they are going to make an appearance as they have their own little theme - akin to a 50s style slow rock n roll 'Happy Days' type number..
It's a shame it ended with just two films, I think even back then everyone would have loved to have seen a third to make a nice trilogy, but alas, Clint was becoming even more popular than he already was and went onto a vast number of other projects..
Buy it, enjoy it.. forget the small continuity errors and it's age.. appreciate what these two films did at the time and again the flawless acting by Eastwood.
The only thing I would have liked is to see a Special Edition of these films, in full widescreen and 5.1 sound, with proper bonus features and documentaries on the making of the films. Hopefully it will happen one day..
