The live teen drama “Riverdale” gets its season premiere this evening on The CW. It’s the show that I’ve discussed a couple of times when I shared the trailers and while the teaser was nothing to speak of, the extended one makes this seem like quite the curiosity of a show. Below is a photo of the cast sitting in that malt shop that they frequented in the comics and I have to say that they look pretty serious. It makes sense since the extended trailer showed a murder and some duplicity among the principle players. The cast and the folks they portray are below the photo.
