Since the specific version you mentioned is 480p WEB-DL , the visual fidelity will be standard definition. This may obscure some of the darker, shadow-heavy scenes intended to build dread, making it less immersive than a high-definition (1080p) viewing.
Horror (2020) is a low-budget Indian horror-thriller that aims to deliver suspense through psychological tension and supernatural elements. Like many films in this specific sub-genre of regional Indian cinema, it focuses on the classic "haunted house" trope but attempts to modernize it with contemporary social themes.
If you are a fan of indie Indian horror and don't mind traditional "haunted estate" clichés, Horror (2020) is a decent one-time watch. However, it doesn't necessarily break new ground in the genre. For a more polished experience, you might want to look for titles on major streaming platforms like Netflix or Amazon Prime Video.
