I can sit here and sing praises about this show but in the end it still won't matter, it won't bring the show back. Bottom-line is that this show accomplished more than any other shows will in five seasons and they did it with only 26 episodes.
Season 2 is one of the finest, best written and planned out seasons seen on television in a long time. The main plot sees Echo (Eliza Dushku) with the ability to maintain her various imprints (personas) after the events of season one, and that further developed into her being able to access those imprints at will turning her into nothing short of a super hero with advanced skills as she plots to take down the dollhouse as well as it's evil founder - Rossam corporation.
As the season progresses, we learn not only of how Echo/ Caroline come to be in the dollhouse but were presented with back stories of Victor and Sierra. Each was given an entire episode where they took the lead away from Echo as the writers tied up loose ends and allowed for further character developments.
Characters like boss lady Adelle Dewitt as well as in-house genius programmer Topher Brink were given opportunities to develop as well in the midst of the massive main plot, as the earlier struggles between good and evil while the latter found love in another evil genius.
One important thing to know for casual viewers is that season 2 does take into account, in fact to a large extend the events that happened in the unaired 13th episode of season 1 "Epitaph One". It is evident that you watch that episode first before starting season 2, especially true for the series finale.
Flash forward scenes of the future in "Epitaph One" comes to play here in season 2, it is extremely interesting and intriguing to watch how those events come to be. Along with a trip to the infamous "attic", return of Alpha, Dr. Saunders, Mr. Dominic and Mellie as well as more disturbing tech and revelation had me hooked all season long.
I guess I'm thankful that we got a second season even though it makes the blow of losing the show so much more painful and harder. This show ended on a proper note (it is very important for me to say that as most cancelled shows don't), the ending was extremely satisfying, not only did they have a proper conclusion for the story arch in the present time line but they took the effort to conclude the events that happened in the future. My only regret is that the show didn't find its way to more audience as it is truly one of Joss Whedon's finest works.
This show will go down as one of the most underrated shows in television history.
I can't wait to own this season on DVD so I can watch it over again and again and again...
