On its opening weekend, the film had grossed $30.5 million, however, as of October 24, 2008, Saw V has received negative reviews, with an approval rating of 15% on Rotten Tomatoes, based on 34 reviews.
Elizabeth Weizman of the New York Daily News believed that the lack of Tobin Bell's character hurt the film: "Bell's deliciously twisted madman was the lifeline of this series, and without him, we're left watching a routine horror flick that might as well have gone straight to DVD...The series began with two major assets that set it apart: the concept of a brilliantly righteous executioner, and the actor who played him. Now, aside from Bell's brief, intermittent cameos, it has neither. So where the original Saw was diabolical fun, this fifth installment is as bloodless as the most unfortunate of Jigsaw's victims." Sam Adams of the Los Angeles Times wrote that "The virtues of the individual films are almost beside the point, since it's hard to imagine why anyone would want to pick up the thread at this late date, but Saw V is a particularly dull and discombobulated affair, shot and acted with all the flair of a basic-cable procedural".
Some reviews were positive, however. British website Digital Spy was relatively positive about the film, however, rating it 3/5 stars and commending the film for its "solid acting, slick direction and suitably filthy cinematography too", while also stating it will "make far more sense to those familiar with the previous installments". IGN awarded the film with 3 out of 5 stars stating that the film ties up most of the loose ends of the previous 4 installments while also having a more straightforward and less complicated storyline. They also praised the traps for being the most inventive and best that the Saw franchise has had to offer.
