I just finished a Hulu rewatch and am so glad I did. I hadn't revisited any of it since it first aired. Though nothing compares to those first times (the light from the hatch window, the end of Walkabout, Desmond and Penny's phone call, "We have to go back!"), I found myself just as enthralled, if not more so, simply because I could remember plot points from 3 seasons ago much more easily since it wasn't that long ago that I watched them.
I remember also being kind of perturbed at the cynics' opinion of the finale. I remember thinking that it was beautiful and fitting and gave me what I needed out of the wrap up of this show, anyway. I was afraid that upon rewatch, I would see those cracks and flaws that others saw. I didn't. "The End" was every bit as moving as I remembered. I cried again at how it illustrated the interconnectedness of humanity, how we really are all connected (in this life, in a parallel life, in the next life, who knows). Am I being too philosophical? Maybe. But I find that increases the enjoyment for me.
After this, I'm not sure what series I'll tackle next. Any suggestions?
