I couldn't be more literal when I say I was on the edge of my seat. Holy cow there was a lot of suspense here! The plot unravels at a perfect speed- it takes it's time, which just adds to the level of suspense. Twist after twist after twist. This was an amazing movie and pushed the limits of PG-13. There was a use of the f-word, plus countless uses of s**t. There was also a collection of other words, such as a*s and b***h. It would be okay for an 8 or 9 year old to watch if you're fine with that kind of thing. There's also some adult humor (which your child will probably not catch) and talk of suicide, throat-slitting. murder, et cetera. I watched it with an 8 year old and she was perfectly fine with it, even if she didn't really understand much of it. If you know your kid, you can decide for yourself. This is a fantastic mystery-comedy and it deserves its 97% Rotten Tomatoes score.
