As has been already said in so many words, this movie is a bit "stagey," with Altman sticking so close to the play instead of taking advantage of the movie aspect. Perhaps as a result, this might have been great to watch on stage, but it took forever to watch on TV. And it is very dated, with lots of racial and sexual orientation slurs. The acting was very good but again hampered by strictly following a script for a play. The setting in the barracks becomes tedious before the halfway mark, and the relatively few actors or especially extras in the background make it look too minimal. Historically, this is probably worth watching, but it is a bit tough to get through.
