No reviews for 'Saw IV,' which is weird

This year's installment of the inexplicably lucrative "Saw" franchise, "Saw IV," opens today, but surprisingly it's not being screened for critics. Still, on the off chance it'll make sense to anybody, here's the plot synopsis anyway:

"Jigsaw and his apprentice Amanda are dead. Now, upon the news of Detective Kerry's murder, two seasoned FBI profilers arrive in the terrified community to assist the veteran Detective Hoffman in sifting through Jigsaw's latest grisly remains and piecing together the puzzle. However, when SWAT Commander Rigg (Lyriq Bent) is abducted and thrust into a game, the last officer untouched by Jigsaw has but 90 minutes to overcome a series of demented traps and save an old friend or face the deadly consequences."
