Run of the mill SF series that goes to places you've probably seen many times before. Budding writers might want to take note that most people don't care about what might happen next year, let alone in 100s of years. so the idea that people travel back in time to our time to prevent a future catastrophe has almost no sense of urgency to an audience. This premise worked with the Terminator franchise, well part of the time anyway, because the threat from the future was to people in the here and now: Sarah Connor, and to a lesser extent Kyle Reese. Plus it had a then relatively novel threat in a near indestructible killing machine. This series has no sense of urgency or intensity. It also adds nothing new at all.

Perhaps to compensate it keeps adding complications that go nowhere. The backstory of Sheriff Jude, the mystery pendant, why the first crossing failed to change history, what happened with Caleb and Rebecca's daughter: there's a lot of stuff that is pointless and uninteresting. And no, that isn't a matter of them being story arcs that might have made sense or been engaging if they had been allowed to play out had the series gone to a second season. They are padding, because the central story is too flimsy to support 10 hours or more of storytelling.

I watched all 11 episodes over the last few days, comfortable in the knowledge that it was cancelled years ago. I was interested to know what went wrong. Suffice to conclude that no injustice was done when this series was cancelled.
