As you may have noticed, the new TV season is rife with paranormal-themed programs. Three in particular are exploring the notion of some type of alien presence. On CBS's Threshold(1), a team of experts is brought together to deal with the fallout from an ET craft landing in the Atlantic Ocean. Over at NBC, the unidentified sea creatures of Surface(2), may actually be alien lifeforms. Not to be left out, ABC has debuted Invasion(3), where ominous beings arrive in a Florida town in the aftermath of a hurricane.
