First, it's true that this is a US version of a Brit TV series. But since Brit TV usually has only 4-8 episodes per season as compared to the 13-20 in the US, the stories have to supplemented to stretch out the season. And the characters have to grow more, also. It works for some shows and not for others.
But this show mostly makes it. Sewell comes across as smart but not smarmy, complex but accessible. Shelton is pretty, bright and brave. This doesn't feel like a show where they are going to fall for each other and jump into bed (or over the shark, for that matter). Adding Omar Benson Miller has added another foil and gives some teeth to the kick-ass FBI. He's got the enthusiasm and really plays well with the two leads.
As for the stories, it's partly X-Files with some CSI tossed in. It's a bit lighter than both but genuinely has some sense of impending doom. Some stories work better than others but this show seems to have found a pretty good balance in the last several episodes.
It's worth watching a couple of episodes. I think it could get better with a little more time to develop. I hope it gets a second season because it could develop into a really neat show with more than a cult following. It gets a 7 for now but there is room for an upwards adjustment.
