Nothing about Species 2 makes sense—not its biology, not its sexual politics, not its inevitable twist ending—but somehow, the film works. No doubt because blond bombshell Natasha Henstridge is back; this time as Eve, a tamer alien who once again spends an inordinate amount of time naked and in heat, “estrogen levels peaking.” Joining her (and equally easy on the eyes) is Justin Lazard, who plays astronaut-hero Patrick Ross, returned from a mission to Mars infected with alien DNA. The hardbody Ross stalks the streets of Capitol Hill (where some of Species 2 was filmed last summer), looking for Ms. Goodbar, leaving in his wake a bevy of rapidly maturing alien offspring. Lucky for us, Michael Madsen, paying off his second mortgage, and Marg Helgenberger, happy to be working, have returned for a second go-round as the clueless alien hunters. The effects are standard, the plot is paint-by-numbers predictable, but Species 2 boasts one precious scene: when Eve, telepathically linked to Ross, tries to help the alien hunters find the rampaging alien. “He’s in a supermarket,” Henstridge gasps. “Aisle One, Fruits and Vegetables.” That the actress manages to deliver this howler with a straight face—and that Helgenberger and Madsen are then able to repeat it successfully—suggests that with better material and a more seasoned horror director, Species 3 might not be such a bad idea.
