Disclaimer: I am a Stallone fan, so this is not by any means an impartial review. Still, I readily admit that Sylvester Stallone has made both good and bad films. This is definitely one of the former, though not typical of his better work.
Stallone will never get any respect for his acting in the mainstream press, which is too bad: if he were an unknown in this role, and had given an identical performance, the press would laud him for his ability to handle subtle bits of comedy interspersed with action and gunplay. But he's Stallone- with all the baggage that carries, both good and bad- so his work is often overlooked.
If I were assisting Mr. Stallone's career, I would have suggested putting this out in film, and keeping 'Get Carter' for video.
Madeline Stowe has always been vaguely annoying to me, but not in this film. For one thing, one has to give kudos to her for her amazing physical shape: she's beautiful, with a figure that a lot of current 20-year-olds should aspire to! She deftly handles both the comic and the pathos of the script.
Rent it with an open mind. I think you'll be pleasantly surprised.
