wtf was that? a sci-fi? lol
What's the point of making the main character a scientist if he doesn't even mention anything about the possible reasons for what happened on earth. There's basically no science at all in this film, while most of the characters are scientists in a pseudo sci-fi film - lol
Moreover - the dialogues were poorly written - most of the time there's no sense of urgency or any sort of attempts to understand the cause of Earth's destruction.
If you wanted to make a film with this type of dialogue, you should have at least made the main characters non-scientists. Even then, of course, it would have been a snoozefest - but at least there would have been some logic to it.
