The common feature of anthology films (or series) being uneven is taken to the extreme in this series. Only the Altman segment can be recommended without reservation. Moreover, the three more dramatic segments are not very good. I think the main problem is while the direction, acting is solid throughout the series the writing is often subpar. Sadwith was the other main creative force behind this series and there is a reason his career is far smaller than Altman's; Sadwith was the main writer and it really shows. The writing is very procedural and a bit too self-serious. However, if you are a Altman fan-he is my favorite director-this is worth checking out or owning if cheap enough. Each film in the series has Altman touches and ideas; it is understandable why Altman was attracted to this set of stories. Furthermore, All the President's Women-the Altman directed film- is a really good hour of TV.
I must also note that it is annoying that you can link the gun's path through like 3 of the films *without* being to fit the other 3 in the gun's lifespan. This sort of writing gimmick you either do or you don't-going halfway is the worst of all possible worlds.
