She was good, once upon a time.
Believe it or not, there was a time when Liza was more than a camp icon and a punchline, there were a few years when she was actually a good actress. Specifically, 1968 to 1972, when she made "The Sterile Cuckoo" and "Cabaret" and a few other films, and actually gave terrific performances!
Gone are the days, stardom ruined her as an actress.
