Johnny Loftus of Allmusic praised the opening track, "Determined", writing in his review, "They nail it on opener "Determined"—one of Mudvayne's all-time strongest tracks, it's a fist-swinging blast of modernized thrash." However, he gave the album a mixed review, writing, "Lost and Found soon falls into the familiar, busting no-one-understands-me lyrics and matching moments of refreshing rawness to stretches of stereotypical 'corporate metal,' a non-genre that's risen up to accept loud rock refugees and the harder side of post-grunge. The energy in "Determined" and "Just" is sapped by the meandering "TV Radio" and "Fall into Sleep," and ultimately Mudvayne gets lost between thrash and diluted Slipknot devotion."
