When 'Lost' was in its prime, it was must-watch television. Remember first watching it, found it remarkably easy to get into, was hooked from the start and was on Season 3 by the end of one week. The general consensus is that the final season is a disappointment and cannot disagree.
"D.O.C." is not one of the best episodes of 'Lost'. It's not even one of the best episodes of Season 3. It's still a pretty good and very interesting episode however and is nowhere near one of the show's worst, as far as the previous episodes go it is significantly better than "Fire + Water" and especially "Stranger in a Strange Land" (a 'Lost' low-point), which were one of the few not good episodes of the early seasons to me.
It is not a perfect episode by all means. It's occasionally a little soap operatic, but it does a far better job than "Catch-22" advancing storylines and the mystery element.
Sun is the most interesting she's been in a while and quite rootable. The flashback and Sun's dilemma are also intriguing, it's slightly soap operatic in the dialogue but doesn't reiterate what we already know and instead builds upon it, and the ending is chilling.
All the acting is good to great. Elizabeth Mitchell is as always terrific as Juliet.
Visually, there is a lot of style and atmosphere, the music is chilling and understated, the writing is thought-provoking enough and the direction has alertness and control.
In conclusion, very good. 8/10 Bethany Cox
