THE SCI-FI CHANNEL DEVOTES THE week of May 23-27 to an array of hip Japanese animated features under the rubric Anime '94 (9 p.m. ET all nights). The festival kicks off with "Dominion Tank Police: Parts I and II" (Mon. and Tues.). In a grim, toxic urban future, our last line of defense against crime is a reckless squad that patrols the streets in bristling armored vehicles, tearing up the asphalt and plowing over everything in their path. In the dazzling "Odin Photon Space Sailor Starlight" (Wed.), an Elvisy looking crew of space cadets on a prototype starship in the late 21st century discovers another civilization. In "Project A-Ko" (Thurs.), a redheaded high school girl with fantastic powers is recruited to defend us against aliens. "The Venus Wars" (Fri.) recounts the bitter battles between colonists on the brutal second planet from the sun. If this is what cartoons look like in Japan, I wish I could spend Saturday mornings there.
