She was a good actress. I enjoyed a couple of her films that she made after 'Clueless'. Her role in 'Clueless' was not really a showcase for her but her later romantic comedies were.
She died at a young adult age when me actors like herself are just getting into their prime and commanding their post adolescent roles. She had great comedic talent and had her own adorable style which was not a clone of someone else but her own.
Everyone is pretty shocked by her death. Foul play is not suspected. Natural causes are. Her autopsy is rumored to be happening today. The results might not be publicly known for weeks.
