I can only remember bits and pieces of this film, the info I'm giving may or may appear in that order but here it goes:
- takes place in space (probably in the future)
- very huge space ships which are literally the home for many people
- protagonists have a small ship though.
- possible released in the last decade. decently cast.
- there's one computer guy who has an robot girlfriend. this character appears after some time into the film. He's sought by the protagonist group for help... he agrees to help but betrays them by giving out their location to antagonist group who then kill him.
- the protagonist group goes to a planet (earth?) to retrieve something and the villain group don't want them to. On this planet all the people and life has died instantly... like in a 'snap'. When the hero group gets here, they see dead decomposed bodies. the scene is like they all died when they were just going about their everyday lives. Cause of death is probably a bio weapon.
The last two points are all I can remember. Nothing else is coming to my mind. It's been bugging me since days and I had no luck with Google.
