Reign

If you want historical accuracy do not watch Reign. I repeat. DO NOT WATCH. At no point does this show ever try to be faithful to its settings or historical figures. Instead, it very clearly tries to put Gossip Girl in a 16th century setting. The lavish parties, prom-like dresses, troubled romances, catty behaviour, model actors/actresses - it's all very 90210- esque. However, I must admit it succeeds at doing just that. No matter how laughable the costumes were, I can't say I wasn't at least mildly entertained. It's quite nice to look at and some of the characters are interesting (if completely inaccurate). And with a supernatural twist, it's quite clear that the creators are simply using the characters and setting as a starting point to tell their own stories. I might keep watching, only to see something different from the CW.
