I think its a bit of stretch to say the Band Wagon is a good example of American conformity, American exceptionalism, gender conformity, etc. I don't know. Maybe I just don't want to see 50s musicals in that light. I don't think they are that intentionally different on a cultural level than the musicals of the 40s. There's just a greater level of finance, expertise, sound and set design. It IS the era of the blockbuster musical. That I agree with.
