Yes, I'm a fan of Lost, and yes I have a tender heart ;)
I think Lost is a very unique series, thus is my favorite of all the times, but I love the Mentalist too, and Lie to me.
And I don't remember me weeping, watching it before, or may be ( surely ) my memory is weak, however, the last episode I saw - Dr. Linus - made me cry.
You know when he gave up his plan ( to dethrone the principal ), in order to avoid bad consequences to his pupil (aka daughter Alex).
And when he said to Ilana that he killed Jacob because he was angry, since he let kill his daughter for the island's sake.
And Ilana let him stay.
I don't know, but when I assist to "love" scenes, where love has his highest meaning, like parents/children kind of love, I'm moved.
Or when I assist to compassion scenes.
And it seems Benjamin Linus is changed, for good...or not.
We will see.
