From dusk till dawn (the series)

I love (the first) movie so I decided to watch the series. I've only seen 2 episodes but I like it thusfar. It follows the story of the movie but it highlights the scenes which are spoken about but aren't shown in the film (eg the bank robbery). I kind of wonder how long the series is, if they keep following the story of the film, they will run out of story after awhile
