The ending was absolutely heartbreaking.
I had been rooting for the Scooby gang to restore Angel's soul the moment he lost it, and although it was interesting to see Angel turn to the dark side, I missed the moments of intimacy and longing between him and Buffy.
The last scene was heart-wrenching to watch.
Angel's last words before he got sucked into the portal of Hell, "Buffy?" made me bawl.
An amazing episode.
