I only dared to watch this when it was edited for TV but I think I could step up to the theatrical release version. Not ready for the unrated version yet though. From what I saw it was terrifying.
Last night I had a Sawesque dream that woke me around 4, convinced me that it was real and made it impossible to go back to sleep. So, I guess you could say that the film is fresh on my mind. However, even though they've, maybe, taken this franchise a little too far, the original was scary and genius and awesome.
