SERIES PREMIERE: If I’m not mistaken, this is the first time in TV history that the founder and chairman of a network has created and directed a television series for his own network. The new network is the El Rey Network, an English-language cable and satellite network with a Latino flavor and themes. And the new show, a 10-part weekly series beginning tonight, is  From Dusk Till Dawn: The Series, an expansion and retelling of the raucous 1996 vampire film directed by Rodriguez, written by Quentin Tarantino and Robert Kurtzman, and starring Tarantino, George Clooney, Harvey Keitel and Salma Hayek. The story is the same here, but with more back-story and depth to fill the additional hours. The first hour is intriguing, and enjoyable, with some of the visual flair for which Rodriguez is famous. But it’s only a tempting appetizer for the mayhem and merriment to come. Zane Holtz and D.J. Cotrona inherit the roles of the Gecko brothers, and Eiza Gonzalez is the first image we see, in a flashback showing the snaky origins of the role played by Hayek in the movie: vampire temptress Santanico Pandemonium.
