I really liked Last Shift. It did a lot with it's low budget and managed to be a genuinely unnerving and interesting horror movie that felt new and original.
I was really quite excited to see Malum. Some more critical folks out there said it was unnecessary, but I really liked the idea of seeing what Di Blasi would do with the original story given feedback from the original, a bigger budget, and time to think.
Well, for the most part, Malum follows Last Shift quite closely. The overall plot is almost entirely the same and a lot of plot points from Last Shift are recreated.
But Malum does add a fair amount of background and extra exposition, either by adding to existing moments from the original film, qnd by adding entirely new scenes.
The problem is, these additions actually take away far more than they add to the film. It was the vaguearies of the original that helped it shine; the viewer being trusted to make connections and fill in the blanks. Malum, by comparison, spells everything out.
There are other issues too. The deranged cultists are so stereotypical that it's hard to take the performances seriously. The special effects, though apparently more sophisticated and expensive, are actually a lot less convincing (I'm trying to avoid spoilers but The Reveal is probably a prime example). And the ending is not only predictable, irrespective of whether you've seen the original film or not, but also deeply unsatisfying and frustrating.
I want to be clear: I didn't hate Malum. I actually enjoued it, despite some serious flaws; it kept me interested and entertained.
But, having seen Last Shift, the "original draft" of the film, I'm left wondering why it was made, because it has literally already been done much more effectively. By the same director, no less!
