I have greatly enjoyed the book and the film. Overall, I think that Heller explored some pretty bleak situations and moral conflicts. He explained that his combat experience in WW2 was not the basis of Catch-22 and, he had no complaints over his service. However, I feel that his conflict experience is so well explored and detailed in Catch-22 that he was totally aware of the forces in play when he was involved in that War. I suspect that Heller had some personal reason to distance his feelings about his War service, using a degree of ambiguity, despite the fact that he wrote about it in detail. I guess that the fact is, Catch-22 works at many levels and I thank Joseph Heller for writing it.
