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."
The critic at Cool Target labeled it "amusing entertainment rubbish" and noted that reusing footage to this degree is unoriginal and dismissive, yet if you can ignore this flaw, Critical Mass is a lighthearted, budget-friendly action film.
