SPOILER: Yes, after watching the final episodes of season 3 now i'm sure, that this is the best episode of lost ever (very very close followed by the final episode of season 3) ! The 23rd palm moment (Mr. Eko praying with Charlie next to him) for his dead brother is one if not the most touching moment in television history. And the soundtrack fits perfectly. The rest of the episode is equally brilliant, telling why young innocent Eko turned into a coldblooded murderer : protecting his younger brother Yemi Eko was forced to kill. Then he became Mr. Eko, a drug dealer and murderer without soul (see memorable quotes). He even isn't scared of smokey and doesn't even bother running away when confrontend with the monster on the island.
