Revisited 2008's Rambo. This easily has to be one of the most violent films ever made (gives Lucio Fulci a run for his money). If I recall correctly, the UK's Odeon cinema chain actually refused to screen it due to excessive violence. There is a director's cut but since it apparently tones it down a bit, I haven't bothered to check it out.
Whilst I certainly wouldn't rave about the film, it is very entertaining! btw My wife and I only own both this and the excellent first film from this franchise.
