For fans of the Saw trilogy, you'd thought that the end of the third installment had wrapped up the franchise quite neatly, and there's absolutely no way another movie can be made except to go backwards in time with prequels. Well, surprise surprise, director Darren Lynn Bousman brings forth the fourth movie of the franchise, and so long as it continues to churn profits, you can bet your last dollar this isn't the last you see of the Saw movies. To be cautious, here's a little spoiler warning for you if you decide to read further. And one reminder, please refresh your memory of the earlier Saw movies, especially Parts II and III, before you go for 4.
