Website Cool Target called it "enjoyable action nonsense" and stated: "Recycled footage to this extent is just lazy and kind of insulting but if you can get past this, Critical Mass is an enjoyably amusing low rent shoot-em up."[2]Moria.co gave the film only one star out of five, calling it "yet another version on Die Hard (1988) and the basic plot template it created of a lone individualistic hero inside a large building/facility single-handedly fending off a terrorist plot."[3]
