Across The Sea There is A Better Episode...
13 May 2010 | by busterkSee all my reviews

I sit on the beach looking out to the ocean, reflecting on six seasons of Lost and the wonderful memories it has given me. I sit waiting for the Jacob/MiB centric episode to arrive and blow me away with mythology, story-telling, and the tightest script of the Lost canon. However, what arrives is soggy with forced scenes, soaked with poor dialogue, and falling apart at the seams.

Allison Janney, a usually dependable actress struggled with the foreign dialectic that resulted it some of the worst dialogue exchanges in the entire season. A season in which the writers have spoilt us with some of the very best scenes and dialogue in the history of television, and yet when it comes to the MOST IMPORTANT episode of all, they resort to the skills of an incompetent writer that has only watched a few episodes of Lost.

What has always made Lost better than any other show is the subtleties and nuances that elevate scenes into memories that will linger.

The writers and creators of this show are very intelligent people which makes their half hearted approach to this critical episode all the more baffling.

They have come out in defence of the criticisms stating that we may not have had the answers we want. But they are again missing the point. It is their show, they have every right to give us whatever answers they want. It's not the answers...it is HOW you give you them. Through tightly structured scenes laced with dialogue that portrays a deeper subtext. Something they brilliantly did in 'The Constant', and more recently in 'The Candidate.' The fans of this show deserved better and so did the hugely talented actors Mark Pellegrino and Titus Welliver. Similar in tone, clichés, and ratings to 'What Kate Does' does not bode well. In the space of 6 seasons there are always going to be episodes of 'filler' quality, but to deliver one at this stage of the story is inexcusable.

The script for this should have been worked on during the hiatus from Season 5 to ensure the glue that binds has no cracks. Unfortunately it clearly wasn't. Instead it has left a bad taste in the mouth that only a stunning finale can remove.

As I cork the wasted pages and toss them back into the ocean, I long for the next instalment and know that across the sea there is a better episode...
