As a kid, it was my introduction both to Mame and Jerry Herman. I didn't understand that Lucy was playing Lucy Ricardo and not Mame Dennis. All I knew was she was funny, her climactic conflict with Patrick was sad, and that the lady from the Golden Girls was HILARIOUS and made me want to learn the Bosom Buddies dance (which, after I recorded it on VHS, I did).
Now, as an adult, I can see all of the movies problems. The footage I've seen of Angela as Mame makes me yearn for a different movie. But the one we have--it still brings a smile to my face.
