It’s hard to overstate how remarkable Upgrade is. The film completely exceeded expectations across the board—the action, cinematography, script, performances, and unexpected developments were all exceptionally crafted! It successfully combines science fiction, action elements, mystery, thriller aspects, along with touches of horror and comedy, resulting in a truly outstanding movie full of surprises I didn’t anticipate. Logan Marshall-Green's portrayal brings believability to the unusual premise through his charisma, and Leigh Whannell is establishing himself as a director I really admire. It’s difficult to find fault with this one; it ranks among the finest films released in recent years and offers enjoyment for a wide range of viewers.
