Judge this episode when the story comes full circle
12 May 2010 | by (Netherlands) – See all my reviews

Well, where do I start? I didn't have high expectations of this episode because i've been disappointed before (Ab Aeterno)! But I guess the reason why I love "Lost" is not because of the answers they give but because of the characters who are undergoing all these adventures. This episode was necessary to explain things that happened in the story but I understand why people hate it. I guess I will judge this episode better when the story comes full circle with the series finale. (and let me say, my expectations are high for the finale!!) Overall it was a DECENT EPISODE but didn't have the same tension and excitement as the last two episodes (The Last Recruit and The Candidate). But it still deserves some credit for the acting skills of Titus Welliver and Mark Pellegrino.
