Shudder is currently streaming a four hour documentary on 1980's horror films called In Search of Darkness, and really, it's less of a documentary than it is a horror movie version of those VH-1 I Love the [Pop Culture Era/Thing] shows that ran in the early aughts.
In the "doc," each year is represented, with horror fans and creators talking about key horror films released in that given year, and for the year 1981, The Burning is one of the films talked about fondly as a precursor to Friday the 13th, with effects make-up by Tom Savini, and a cast that includes Jason Alexander, Fisher Stevens, and the guy who played "Ratner" in Fast Times at Ridgemont High.
And sure, it's a hoot seeing George Costanza as a "teenager," but in all, the movie is just OK. I didn't think it did anything better than many of the slasher movies that came after it, but I guess it deserves props for doing some things first.
Strangely, it's not readily available to stream or rent, even on DVD, but there is a pretty good print available on YouTube, which is how I watched it. It's embedded below.
