War at the Warfield was well received by critics, debuting at number three on the Billboard DVD chart, and sold over 7,000 copies in its first week.

[13] On December 21, 2001, it was announced that the original drummer, Dave Lombardo, would "temporarily reclaim his place behind the drums on the next leg" of Slayer's God Hates Us All tour.

[13][14] Bostaph described his time with the band as "an unbelievable ride with Slayer, playing with these guys has been an incredible high point in my career", and that he is "really grateful for the experience".

[16] William Ruhlmann of Allmusic commented that the DVD "serves as both a fan's statement on Slayer and a good representation of the group's music and performance style.

"[17] Jon Wiederhorn, an editor for MTV, said that "Slayer's new War at the Warfield DVD isn't one of those home-video concert releases meant to distract fans during a lengthy gap between records—the group already has ten songs written for its next LP, which should be out by April.

"[10] Andy Patrizio of IGN awarded the DVD seven out of ten, mentioning "the ferocity and intensity is still there, just a tad slower," and summarising with the statement, "if you're a Slayer fan, or into thrash in general, you'll love this.

"[18] Patrizio criticized the video's direction, observing that "the camerawork is full of fast, MTV-style cuts, which, combined with the flashing lights, is more headache-inducing than the music.
