This script was written to accommodate Anissa Jones (Buffy), whose leg was actually in a cast at the time. 

The maimed-leg prank was really way-out gross. But it seems that is the kind of weird humor the show handles.

This is a strong episode. The subject of guns at school is dealt with in a realistic way. Acting is top-notch and writing really makes you live the intensity of the plot.

This is the episode that should have led off the series but, according to executive producer Aaron Spelling, the network was nervous about it since it deals with witchcraft.
