I gave it a whirl when it was on sale for $5. While the gameplay was mediocre like you said, it was worth the ride. Some set pieces were really cool. But like anyone who loved it will tell you, it's all in how it makes you feel. When YOUR decision -blam!-s everything up, you feel it. When faced with two options, I picked the one that made clearing out enemies a TON easier. And I ended up accidentally killing innocent people because of my laziness and worrying about myself instead of others. And because of it, I felt bad. But I liked it. It's one of the few games that make you feel things besides just fun. A different choice in the game had me sit the controller down and debate which option to take for at least ten minutes. I'd say that's worth the money to buy it, especially how cheap it is now. Trust me, the story and every part about it is worth it. It keeps you guessing, gets you emotional, and I feel like I really learned something from the game. Play it. No it's not the best GAME ever, but it's a hell of an EXPERIENCE, which is what you should expect out of it. And it's just a well-polished game.
