I was gonna start a thread about this called Season 7 - Bring it on!
There's enough for the story to continue. Hurley is in charge of the island with Ben at his side. Cindy and the Others are there and so are Rose, Bernard and Vincent. Kate, Miles, Frank and Richard are on the mainland having to deal with their disappearance and return, and they can even visit the island. Jack and everyone who's dead can appear as ghosts or in flashbacks to the missing three years. We can even dig deeper into the island's mysteries. There's a lot of story potential still out there.
