Not a good movie but it's so interesting and weird to see Gary Burghoff interact with alternate universe M*A*S*H characters. Robert Duvall as Frank Burns is *chef's kiss*.
I'd actually recommend watching this AFTER the series even though it came out before so you can have a stronger basis to analyze how similar/different the character portrayals are. I like the cast in both but, come on, Alan Alda IS Hawkeye. Sorry Don.
