"V," 8 p.m. KFSN (Channel 30.1): If you are old enough to remember the original science fiction series, the changes for this updated version of "V" will be quite obvious. The new series shows the influences of the 9/11 attacks to create a threat that is much harder to detect that the very military operation in the original. The new version also benefits from advancements in special effects. Acting was an afterthought in the first "V" often reduced to Marc Singer standing around without his shirt. This time the series features solid performances by Elizabeth Mitchell, Morena Baccarin and Scott Wolf, to name a few. This all goes together to make the new "V" a welcome alien invasion.
