MTV unveils its first daytime soap, Spyder Games (3 p.m., MTV; repeated 8 p.m.), a sort of spoof, but sort of not a spoof, of the genre. The show revolves around the bed-hopping antics of a Russian-born video game company president and his horny offspring. On a rerun of The King of Queens (8 p.m., CBS), Doug and Carrie have opposing opinions about Deacon's affair. Biography (8 p.m., A&E) concludes its profile of the French impressionists with a two-hour installment. Bride-to-be Anne Heche begins her stint as a woman with Tourette's syndrome who falls for John on a rerun of Ally McBeal (9 p.m., Fox). Angel (9 p.m., WB) moves to its new day and time. It's weird, but we'll get used to it. It's a rerun, by the way, of the episode where Angel discovers a Wolfram and Hart connection to a shelter for runaway teens. The shelter director is a woman named Anne, and, yes, eagle-eyed "Buffy" fans, this is the same "Anne" from the "Buffy" episode a few seasons back where the Slayer ran away to Los Angeles and saved a bunch of runaways from a demon hell-prison.
The new TV movie Snap Decision (9 p.m., Lifetime) stars Mare Winningham as a mom wrongly charged with being a kiddie pornographer when she lets her photographer friend (Felicity Huffman) take some innocent snapshots of her kids. The four-part documentary series Vietnam: On the Frontlines (9 p.m., History Channel) looks at the war from the perspective of veterans, historians, war correspondents and news photographers.
