I'll echo the Edge as very good. It's written by David Mamet (Glen Gary Glen Ross) and the action scenes are incredible (and realistic, with no CGI). Bart the Bear was a famous trained bear who is in just about every nature movie of that era requiring bears.
The Siege of Jadotville is a modern Irish / South African film (which is why it doesn't suck) that tells the story of a Zulu-type battle the Irish Army had versus overwhelming odds during the Congo Crisis of the 1960s, while acting as peacekeepers.
The film is basic old fashioned action moviemaking ,the way films used to be--straightforward plot without any Christopher Nolan flashback scenes, good action and conflict, little to no women (shoutout to the fantastic Old Henry) and a nice ending.
The only complaint I have is that some of the minor characters and subplots were confusing to those who don't have a background in 1960s Congolese history (for example, the opening scene is the murder of the Congolese Prime Minister Patrice Lumumba, and I didn't know it was anyone of power or political importance until reading more. It's helpful to read a bit about the real life incident, but that also ruins the plot a bit--once you know how the battle ends, there's not a huge point to the movie.
It was very well acted and appears historically accurate. Crazy to think that Irish and French were fighting each other over the Congo. If you like the film, read up on Congo Crisis after watching it.
Finally, a war movie where I can root for the white guys and not be made to feel guilty about it.
