Being familiar with the game, it was surprise to find out that 1) it was based on a novel that would count as a prequel, and 2) it was well thought out and drove home the originality of such a villain living within us.
Unlike the game, this is more tame and has no need for action and bullets blazin'...not that there's anything wrong with that :0). It's just that in here, it give a more scientific (yet easy to understand) approach to the series' overseas (in many ways) origin and climax, and also shows that, as cheesy as it sounds, love conquers all. It is a little slow at first, but there are things that keep your interest, so yes, it really is a good watch, even if you're not a fan of the game, or didn't know it was a game at all. It's a rare find, but it's worth a try even once :)
