The overall story of Dead Shadows feels like an homage to 80’s scifi horror, in particular Night of the Comet.  In the first five minutes, we see our protagonist, Chris, watch his parents die after the Halley Comet flew by. Although it looks like modern times, we are suppose to believe ten years have passed. Chris becomes a tech nerd who slowly builds a relationship the girl next door. The first act makes the story feel like a slow burn Ti West movie. However, that script got thrown out for something that barely resembles a shooting script. The rest of the movie is a montage of campy and somehow diverse mutated parisians melting or ripping each other to shreds. Some scenes are stacked on top of each other in a way where it would have made more sense if we were given a missing scene title card. The only continuity that remained intact in the end was the characters consistent bad decision making. For example, why is he making out with that naked spider woman? Overall, this is a cheaply made scifi horror which gives it a nostalgic flavor. Maybe if they dumped the first act the movie would have felt more focused.
