In a word (well, two, actually): it sucks! That being said, "Curse of the Zodiac" was marginally better than Lommel's previous flick about the Zodiac Killer. This atrocity was apparently set in 1978, and dealt with the Zodiac Killer taunting some writer for reasons unknown. He is still killing, but unlike the real Zodiac Killer, Lommel's version stalked only women and killed them by putting his gun in their mouths and pulling the trigger; it is a matter of fact that the real Zodiac Killer never did anything remotely like that. It's also a matter of fact that 4 of the Zodiac's 7 known victims were actually male, and he was never known to stalk and kill lone women, but then, facts don't seem to be anything that Lommel cares about.
The Zodiac harasses some writer a lot with phone calls, and cusses quite a bit (as mentioned in previous reviews); if all of his cussing were edited out, half the movie would be gone. It's apparent that Lommel has no talent for writing (or directing, for that matter, since he doesn't appear to have invested in anything other than his camcorder that he doesn't know how to use very well), since he couldn't think of anything else for the Zodiac to say. This flick itself was pretty pointless, it didn't seem to have any direction at all and I wondered the whole time where it was going. After it was over, I wondered why I even sat through it (I actually fell asleep two or three times, and the parts I missed made no difference at the end). I will say this, however: the heroine, played by Cassandra Church, is pretty cute, and it does look like she was making an effort unlike most of the others, who gave the impression they were making up the dialogue off the tops of their heads (and, if that's the case... what dialogue did Lommel actually write???).
The heroine had a psychic connection to the Zodiac, and he was also psychically aware of her. At the end, it's implied that the Zodiac killed her psychically... and then, I remembered where I saw this movie once before: "Fear," a TV movie that came out in July 1990, starring Ally Sheedy and Lauren Hutton. Ally Sheedy was a psychic who connected with a serial killer, who in turn was aware of her and played mind games with her. At the end, however, he was the one who was killed, not the psychic... and it looks like poor old Ulli couldn't think of a better plot and so ripped off an old idea and hoped no one would notice.
This gets one star only because there are no zero star ratings. Give it a miss, unless you want to see the cute Cassandra Church...
