One of the best films to come out of the "action era" of the 80's (i.e. Schwarzenegger, Stallone et al) was First Blood. Not so much violent, as tense and actually rather exciting.
This was followed up by Rambo:First Blood Pt2 and I can still remember the news feature on the 9 O'Clock news saying how violent and deplorable this kind of film was. It was also very anti-Russian which seemed to be a theme for Stallone for some reason (Rambo 3 and Rocky 4).
Then Rambo 3 came along. 1 man against the might of the Russian Afghan based army...and the 1 man wins. Hardly realistic but good fun.
Each film scores high on it's own merit. The 3 of them are still timeless action classics in my book and if you want a good blast of an action film there is nothing better than throwing these on the old VCR.
If you haven't seen these films but are a fan of the action genre then I heartily recommend them and you will enjoy them very much. They haven't aged at all and there is some superb stunt work in all 3 films and plenty of shooting and explosions especially in the last 2 films.
It's a shame these kind of films don't seem to be around these days as they really are good fun if you can forgive the lack of deep plot or Oscar winning acting. Overall...3 classic films which no action fan should be without.
