I don't want any hard spoilers, but maybe you could put in spoiler tags whether it wraps up as a self-contained story, or if it got cancelled with a lot of loose unsatisfied plot threads? The premise sounds good, but if it was obviously written for more episodes that never came... I'm real wary of shows like that.
(eg sucked that Firefly was only 1 season, but at least it stands on it's own; shows like the 4400 not so much)
