l.S.S is a good, solid psychological suspense movie. I rented it but now Im buying it to add to my elite personal collection of favourite movies. I thought it was beautifully shot, well-- acted, well written and the story was interesting and suspenseful with the undertone of the conceptual conundrum of national allegiance, loyalty and honour vs friendship, morality and personal integrity. It highlights the different reactions individual people would likely have when faced with a serious dilemma. However, like most psychological suspense movies you have to really concentrate and understand it to get the most out of it. Perhaps the poor reviews were from people who didnt have time to watch it properly??
