I know she got a lot of stick for WALL STREET, it wasn't as if she was doomed for the start due to how poorly written her character was, though I do concede she was terrible in STEEL MAGNOLIAS. Even I can't give her a pass for it.
Nevertheless, in SPLASH and ROXANNE, I found her lovely and engaging and likable. It isn't like today where you're asked to like the leading lady. Back in the day, the leading lady won you over with her irresistible charm.
Even though she played many kind and sweet ladies, Daryl Hannah was even more effective at playing the psychopath which is surprising when you know her from SPLASH. In the KILL BILL films, she's deadly and vicious as Elle Driver and in BLADE RUNNER, she uses her seemingly sweet person to keep us assuming Pris, the replicant, is harmless until we see her creepy smile or when she attacks Deckard by twisting his neck.
