This the fourth and final season of 4400, unless the network brings them back. The only reason I did not give this five stars is the ending. Be forewarned, seasons 1-3 were good, season four is very good, but ends mid-story.Other than that, if you enjoy Sci-Fi, give this show a viewing. The premise of the series is pretty cool; 4400 people (almost all Americans, ironically) were abducted from various times and returned at the same time with special gifts.[powers]By season four the characters are getting developed in way that is defineately interesting, however one can tell that the writers are making some up on the fly. They probably were not sure if they were getting one or two more seasons; anyway it is worth watching. If you do, make sure you at least send an e mail to the network ( I think it's CBS) to request another season. They end it when it[storyline] is going real good.Do not start with season four, start with first season.
