Ok, just finished the screener, last night. Hate to say it, but it could go either way. In a nutshell, it's "Jurassic Park" meets "Lost" with a little "Avatar" thrown in. They even found a younger version of Evangeline Lily.
The first hour really rushes the backstory about how the central characters end up back in time some 85 million years. The central character has to bust out of prison in order to get to the ...Stargate (for lack of a better term) in time. We never see how he does this. And I think I picked up one piece of dialog later in the second hour that made reference to something that was edited out of the first hour.
That said, rushing the backstory was a good idea because there's little there that endears you to the story or the characters. While too obvious of a rip-off, I'd have preferred they start back in time and fill in the gaps through flashbacks. But, as I said.. it's been done.
While I'm dredging up "Lost," let me add that there's a "Lost"-style puzzle introduced in the first episode that producers are obviously hoping freeze-framers discuss and dissect it much like they did the Dharma hatch "map."
No doubt this show will get picked apart mostly for some of the scientific liberties they take. Others may get tired of all the "green" preaching. But, after they get by the backstory, it does get a little interesting. It's no "Lost," though. Not yet, anyway.
OH.. look for the cameo by President Obama right before our "hero" gets to the Stargate. At least I THINK it's Obama. You tell ME.
Walking the fine line between jaw-dropping and a plain ol' yawn.
