Except for the first 10 minutes of action, Private Ryan is an insult to all who served in WW-II. It portrayed many of the GI's in the movie as a bunch of cowardly, selfish, self-centered, spoiled brats. Kind of like having a bunch of politically correct liberal college students from 1999 sent back in time to the 1940s. (Geared I guess to appeal to a modern day audience.)
Apollo 13 because it is an exact copy, word for word, scene for scene, of a PBS documentary that was made 5 years earlier. The documentary showed the real thing and the real people. The movie is a joke watching the actors pretend, after you have see film footage of the real thing. Real men thinking they are going to die; real ground crews and the real mission director working to save them; real spouses thinking they are going to be widows, and their children reacting to what happened and talking about it afterwards. (It is available on VHS.)
