When things cannot get bigger, they do. This episode was massive, I most say. Really, really impressive. One of the best. It had everything - the mystery of the ancients, the threats, treachery, lot of action and stunning, impressive visual effects. The Antartic scenes - the whole things with thrones and Ancients outposts.. it was just amazing. Also the emotions involved - Teal'c trying to say what he think but there was no reason. Ofcourse Sam.. and O'Neill saving Bra'tac when it looked so hopeless.
I just say - I loved the episode. The way it was massive, the story, effects, the sad ending. It was perfect.
