it is cool to see how they wound up the way they are. but, i think halloween was the only one that didn’t ever show how michael myers wound up as a mass murderer until the rob zombie remake. Friday The 13th Part 1, shows Mrs. Voorhees killing and then explains about jason, and Freddy Vs. Jason explains how Krueger was a child molester or murderer (i forget which). And the towns people burned him alive.
