I had very mixed emotions at the end of the show-- I loved it, but at the same time I hated it. Everything that we knew and depended on changed in a mind-blurring hour of one shock after another.
As I try hard not to read spoilers, I was absolutely stunned at the end of the episode-- the Alliance has been destroyed! It seems that Sydney's mission has been accomplished...but has it really? Our Alias journey has made a sharp and unexpected turn, but JJ and the writers of Alias have not let us down so far--Alias has just gotten better since the pilot, and the writers have proven themselves in their loyalty to the integrity of the heart of the show.
Yes, the plot has had a dramatic shift, and the premise has changed. But with such a fast-paced show, you have to keep it moving before things get stale. They have left so many roads open to take--I'll admit that I don't know how they will keep it fresh every week now, while still staying true to the Alias we know and love, but all I can do is have faith in the talent that's behind it, and trust that they won't let us down. It'll all be okay-- this is not the end, but an exciting new beginning!
