Hitchcock said there is no suspense in a gun shot, but rather the suspense is in waiting for it. That so well applies to Dog Run. Things appear to be going just fine, until things get a little creepy amongst the human characters, and just keep getting creepier. Truly an edge of your seat thriller, but I would recommend younger viewers go elsewhere since Dog Run would definitely prove too suspenseful and downright scary at times for them. Dog Run is much more thrilling and suspenseful than the plague of recent major motion pictures claiming to be the same. I wish I had a DVD copy to show my friends this past Halloween. It would have been more of a fright than anything else I've seen in too long.
