"The alien itself is a disappointment, as the filmmakers’ intriguing idea of having a xenomorph infect and thus absorb the DNA of a quadrupedal animal is squandered on a garish puppet creation that moves in jerky, dissonant steps that completely divorce the creature from the environment. This robs the alien of even a hint of menace, barring a few close-ups that keep the image limited to the xenomorph’s face and teeth. Prefiguring an issue that’s plagued all future Alien movies in the CGI era, the depiction of the xenomorph so casually in full view saps much of the suspense that the first two films wrung out of keeping the monsters hidden or partially glimpsed. Once its definitions are set, the creature loses its amorphous, undefinable shape and size, limiting it to something comprehensible. The lackluster alien undeniably drags down the proceedings, but the film maintains a consistently bleak atmosphere that elevates it above its sloppy sequel and the more self-conscious philosophy of recent prequels by staying truest to the simple hopelessness of the original film."
