Likeable characters in a slasher?
I honestly think this is one of the few slashers in which there are characters who you feel sad for when they get violently killed. Now, they are not three-dimensional living and breathing specimens but they are not ultra-obnoxious and so despicable that we root for them to die. Sure, Alfred is very annoying but even he is not made out to be vile and irredeemable. Even the bad guy has a moderately sympathetic backstory.
Most of the slashers today wallow so much in gore and viscera that they forget that we need atleast somebody to root for. In most of the good FT13 movies, we had likeable characters like Alice, Ginny, Megan, Tommy(From 4 and 6).
Likewise, in the Burning, most of these were normal, decent kids who were getting butchered like Woodstock, Dave, Todd, Sally.
A very underrated slasher.
