Of all the varied strands of post-9/11 cinema, the speculative film–the one showing us what life would be like if it were slightly (but significantly!) different–is by far the most superfluous. Last year’s lame “Right at Your Door, which sank right into oblivion, pondered a world where Los Angeles is hit by a biological weapon: suffice it to say that civilians panic, human bonds are frayed, and military authority acts really mean. Strangely, Bryan Gunnar Cole’s Day Zero (not to be confused with another desperate stab at topicality, 2003’s Columbine-riding Zero Day) could be Door‘s unasked-for spin-off. Here, a recent terrorist attack on L.A. is referred to, right along with 9/11, making its world an ostensibly more vulnerable one in which the draft has been reinstated. Of course, the return of a draft would probably be more dependent on the situation in Iraq and the one on Capitol Hill, but first-time film director Cole and screenwriter Robert Malkani (whose only other credit is the brilliantly titled Dot.Kill) don’t really care about realistic politics. They’re more interested in the “human side” of this fictional issue, which they seem to know just as little about.
