I just finished it last night, and I have to say, that while tedious at times, the last act is so suspenseful, and the flaws are so few and far between that it's a game I'm glad I bought (my first pre-order, as I keep mentioning), and compared to most, if all Rockstar games, it's only the 2nd game of Rockstar's that I have beaten (The 1st was Manhunt, which makes me feel better that I can beat Rockstar's games that aren't Grand Theft Auto) and enjoyed.
All in all, I would buy a sequel if one were made, and I want to play it all over again.
