Glad you enjoyed it! I saw it in the theater as child and it was a great vision of a future that people actually lived in, complete with labor disputes and coffee cups. At the time it was revelatory.
Yes that “used future” quality! It absolutely feels lived in. I really prefer the practical effects used to anything we do with CGI now, also. I loved the little chest alien and the big metal teeth guy with the wet head and you can just feel how much love/attention went into their making and design.
