I am up to episode 30 out of 58. The second season is interesting but one of the mistakes the show made was by writing out the Baker character for comic relief. Now I do remember watching the entire season in first run . At the time I watched the second season and expected more action from the two part opener. The second season is more about psychology and the episodes are still worth watching but are not as good as the first season. The exception is episode 27 with the deranged sniper Sgt Block, The episodes are good because they are fresh. I never viewed them so they remain interesting.
Thus far the best episodes
1) The episode that tells the tale of the Montangards. Communists feign outrage about the treatment of indigenous people in American history but abuse them in the present.
2) The Season One finale that has the platoon capturing the same hill 3x. The war objector saves his peers and is badly injured. This is the last time we see Horn who was the best scripted part of season one.
3) The USO episode where the singer Long John looked and reminded some of Jim Morrison. In this case an epileptic becomes a rock musician after flunking out basic. He participates in a firefight and thinks he is invincible. He gets a friend killed trying to retrieve a saxophone. He sacrifices his life to save Taylor.
4 Sgt Block. The sniper becomes psychotic and has to be put out of his misery.
5) The episode where the Communist Doctor is ordered to kill Prisoner Taylor. The tunnels are portrayed pretty well.
