old blog: double features

This is the weirdest DVD double feature I've found at the video store I work at:



I can't figure out why they would skip Substitute 2: Schools Out. Instead it got a separate release.

2 and 3 both have Treat Williams. Why wouldn't they release the first one alone and then 2 and 3 as the double feature??? They could have given it a goofy name like the The Substitute: The TREATment Set. or whatever.
