Covenant -2017- Dual Audio Bluray 480p ... | Alien-

I need to make sure the analysis is thorough but accessible. Avoid spoilers if possible, but since the user asked for a deep piece, some plot points might be necessary. Also, touch on the technical aspects of the BluRay—does the 480p make a difference in watching the film's details, or is the story the main focus? The dual audio might be for different languages, but there's a possibility it's an Easter egg with director commentary, so checking that would be good.
