That was quite good
Extant really surprised me this season. I thought it was just OK last season, and then the changed direction for this season threw me for a while. But once I allowed myself to go with the new flow, it carried me, and by the end I found it pretty exciting. They kept the right characters, and adding Jeffrey Dean Morgan turned out to be a winner. Tonight's final episode serves as a suitable series finale if Extant ends while offering a thread to keep the series going if CBS renews it.
