I've just finished this "game" and I was seriously underwhelmed. I'd give it a 5. Sure its pretty, but Its not pretty enough to make up for the slow pace and fragmented story. It feels like its starting to go somewhere at points but the conclusion isn't one I was happy with. I feel I was very patient with it and gave it a good honest chance but there was no emotional connection to any of the characters.
If a game chooses to be an interactive film it needs to make much more of an effort to keep the story and characters engaging.
