Clueless is a modern day adaptation of Jane Austen's Emma. Cher, the Emma-ersque character is played by Alicia Silverstone - rather well I thought!
Half the fun of watching this was working out who was who, drawing parallels with the book and today's world. I also walked away feeling like I shouldn't like Cher and her friends, but I did. Best of all, it does stand alone. While having an understanding of Emma gives you some aha moments, it is not necessary. It was pleasant way to while away an afternoon.
