This is one of the best shows of the season. The storyline is strong, with effective flashbacks that help drive the plot. I think the writers will keep us guessing who the real terrorist is until the end, and I plan to stick around to find out. Each character is compelling, harboring a secret of his/her own. Sure, the show is a bit far-fetched, but it works. A mystery is only as good as its storyline, and this one is great. This intriguing show is worth a watch.
