Not bad as far as Syfy Channel fare is concerned. It had a decent plot. Strong enough for suspension of belief to carry the story. But get real ... the US military running rampant all over Stonehenge on the British Isles. I don't think so. And the travelling from Britain to North America and back seemed awfully fast. At least in the climax they actually mentioned a supersonic jet. I think the writer was trying to Americanize the story when it wasn't needed. CGI was cheesy at times but bearable for what is essentially a B movie. Despite the flaws, the characters from Supernatural, Stargate Atlantis, and Highlander did a good job of carrying the story.
