Invasion

Something strange is happening in the town of Homestead, Florida.  As the town works to rebuild itself after a hurricane, people begin to notice lights under the water and that other townsfolk are behaving oddly.  After the sheriff quarantines the town, two colleagues investigate the mysterious lights.  Eventually they become aware that the lights are related to sea creatures who are gradually hybridizing the townspeople, and that the government is trying to cover it up.

Creator and main writer Shaun Cassidy ('70s pop artist and co-star of The Hardy Boys/Nancy Drew Mysteries) envisioned five seasons for the show, with focus on certain characters and an ultimate reveal of the mastermind behind the invasion and its nature.  Cast member Tyler Labine mentioned in a 2010 interview: "The idea of the show was we never going to win.  What was happening was not a invasion at all, it was an evolutionary step.  So we're basically going to spend five seasons trying to win this battle we can't win."

Airing on ABC from September 21st 2005 to May 17th 2006, the show had mostly positive critical reception and was nominated to the 32nd Saturn Awards for both Best Network TV Series and Best Television Actor.  Unfortunately the ratings were such that the network decided to cancel it.  There were rumours of a move to The CW but a deal was never reached.  Shaun Cassidy commented after the cancellation: "I think there were unrealistic expectations that any show following Lost should do better."

As with many series, Invasion did somewhat better in the European market, airing in several countries between 2007 and 2009.  By that time, all the episodes had already been released as a  DVD box set.
