I watched the first three episodes, and quite frankly this show is a complete mess.

It can't decide whether it wants to be a period drama, a detective show, urban fantasy, a war story... The dichotomies between these genres are too big, and the writer makes a crap job of marrying them together. They're not mixed well enough for the flow of the story to be smooth. It's like watching a show with multiple personalities disorder.

The dialogue isn't all that great, the timeframe of events is unclear, and there's no spark between the lead couple in the slightest. They have some type of chemistry, but it is definitely not of the romantic kind. Also the pacing is all wrong. There are way too many scenes so unnecessarily long. It made for a very boring watching experience.

As for the cast, they're not the best of actors, but they're not the worst either. However, I need Cara to just pick a freking accent and stick to it. I've seen her in interviews and I know that's not what she sounds like, so why have an Irish accent for some scenes and not for others? The accent wasn't necessary in the slightest. So why even add it if you're not gonna be great at it? So pointless.

If you wanna watch an Amazon Prime show about a wartime love story with fantasy elements, just go watch The Man in the High Castle. The first season is infinitely better, I promise.
