Apparently fluffy Sci-Fi channel show Eureka, about a town of zany geniuses who do silly things, is just too dark. Even though every episode is packed with sappiness worthy of Full House, its creators have vowed to make it even "lighter" this season, packed with ultralite parodies of movies like Groundhog Day, according to Sci-Fi Wire (how do you parody a movie that is already a comedy?). Let this be a lesson to other scifi shows, such as Jericho, which could really have used a little lightening up. And how about 4400? Why not turn each episode of that into a "funny" parody of a movie like X-Men? That could have been both shows' tickets to renewal if only they'd known about this whole lightness thing. [Sci-Fi Wire]
