After two fairly lackluster (by LOST standards) opening episodes, Season 2 scores its first really solid hit with "Orientation". This is a terrific episode that works on multiple levels: it briefly explains who Desmond is and what he has been doing down at the hatch; it introduces the Dharma Initiative and its orientation films (making it also clear that this is just one of many stations they have around the island); it also introduces some new characters - Eko and Ana Lucia - in a very surprising fashion; but above all, it develops the "Man Of Science, Man Of Faith" theme even better than the episode that had that title! Both Matthew Fox and Terry O'Quinn are outstanding here, and some of their line deliveries ("I married her", "It's never BEEN easy") are so good they'll give you chills. Hurley provides some typically funny comic relief (he finds the room with the food supplies!), and if all that is not enough, there is a guest-starring role for Katey Sagal AKA Peggy Bundy in Locke's flashbacks! What more could you possibly want? ***1/2 out of 4.
