This movie felt familiar, especially after seeing 'Lucy,' even though it was actually made earlier but came out later. The two films share similar ideas, although they’re different kinds of movies. I found Scarlett Johansson's film to be quite enjoyable, and this one looked good too; watching it afterward helped me appreciate the science behind it, rather than just accepting it as magic. What stood out were the standard horror movie elements—sudden loud noises and jump scares. It features a small cast and takes place over a single day. The writing, direction, and acting weren't bad at all. The locations felt right for the story, and impressive special effects weren’t necessary. It centers on a tiny team of medical researchers developing a serum to revive the deceased. When their employer shut down their project, they resolved to rebuild it as proof of their ownership. Then things went wrong, leading to destruction before the film concluded. It's more of a science-fiction thriller than a typical horror movie, but it uses familiar horror techniques in its presentation. The plot is easy to follow, aside from the scientific aspects. People who aren’t comfortable with basic science might not grasp those parts and would probably just see another predictable horror film. For me, this is an average movie—worth watching once because it's short and moves along at a good pace. _6/10_
