This week we’ve got a guest post from Heather Hughes.

For years Lost has confused us with its time-travelling island, sinister smoke monsters and seemingly misplaced polar bears. With every season comes new, often unsolved, mysteries that stump even the most loyal of Lost fans. Until now, that is. Lost’s sixth, and final, season has kick-started, and it promises to give us answers. Finally!

“I think there are people who have certainly figured out significant pieces, but they don’t have enough information yet,” Damon Lindelof, the show’s co-producer, has explained: “Starting with the season première this year, the remaining clues necessary to figure out where we’re going to end the show are going to begin to fall into place.”

When we last saw the castaways they had just detonated a hydrogen bomb, which they hoped would destroy the island and thus change their past (or should that be future?). Of course, as is always the case with TV shows, things didn’t go to plan. Shots were fired, Sayid was hit and Juliet was dragged into a well of explosives. The finale left viewers with no end of queries. Is Juliet dead? Has the island been destroyed? And to the extra-observant, why was the title screen white instead of black?

The big question on most people’s lips, however, is not about the kamikaze castaways, but on how the Other’s leader (John Locke) is still walking around when he’s dead, strangled by Ben back on the mainland.  At first it was assumed that Locke had somehow come back to life, but later this was proven far too preposterous an idea – even for Lost – when his carcass was tipped out of a coffin at the end of season five. So, who exactly is the intruder? And why is he so eager to kill island boss Jacob? Come to think of it, who the hell is Jacob anyway?

Kudos to the show’s creators: this season’s double-bill début has already started to answer some questions. Infuriatingly, it’s also unearthed more mysteries too. One thing’s clear; deciphering them is not going to be easy. The newly-scripted shifts between alternate realities will make sure of that.

It would take hours to list all the theories and unanswered questions amassed throughout Lost’s lifetime.  There’s talk of it being a dream, or a form of hell, but no one really knows — well, except the show’s creators (you’d hope).

So, what do you think of the first few episodes? Any theories on how it will all end?

You used to be able to dip in and out of TV shows. Soaps aside, television writers were usually happy to helpfully navigate characters back to where they started by the end of an episode. And if you missed one, unless it was a two-parter, it made no difference whatsoever.

Now if you watch a programme, it’s like a relationship. There’s commitment involved. Lost and I split up after about six months because I didn’t think it had a clear life plan and was basically winging it. Heroes and I are still together, but we’re really just going through the motions at this point, with dead, dead eyes.

All of which is to say: will FlashForward betray you and break your heart?

Ideally, I’d now trigger a vision of myself six months in the future watching the finale to check whether or not I’m smacking myself repeatedly in the head in lieu of putting the remote through the telly. What with physics and all, that’s not really feasible.

So make your own mind up:

The good

• The premise is brilliant. Loosely based on a 1999 Robert J. Sawyer novel, the action kicks off when the entire human race blacks out for two minutes. During the blackout, everyone on Earth experiences two minutes of their own life, six months in the future. Then they wake back up. There’s mass death and global devastation, because cars and planes can’t drive themselves for two minutes. And everyone wants to know – will the visions come true? How do I get to where I saw myself – with a different partner, unexpectedly pregnant or just dead? And most importantly for our FBI protagonists: how did it happen and could it happen again?

• The execution of the premise is brilliant. Every episode so far has had some memorable apocalyptic visual, like an airport full of broken planes, a playground full of blacked-out children or hundreds of crows crashing earthwards at the same time. Basically, if they start floundering, they just need to get back to the central concept of the show – there’s so much potential depth there.

• Joseph Fiennes, Jack Davenport, John Cho and Courtney B. Vance, among other great regular cast members, can sell even the lousiest dialogue, of which there is much. And even the tiniest roles are filled by good, classy actors, like Alex Kingston, Gina Torres or Shoreh Aghdashloo.

• I think there’s actually a plan. The fact they’ve seeded actors like Kingston in meaningless roles early on suggests they’ll have key parts to play later, and that these have been thought through in advance. The creators have also said they’ll catch up to the flashforwards by the end of the first season, which helps keep the plot tight and contained, unlike Lost’s multi-season sprawl.

The bad

• I still know almost nothing about any of the characters. It’s like they took some actors they liked and assigned character traits and jobs to them. “Hi, Joseph Fiennes, you can be an FBI agent who’s a recovering alcoholic.” “Oh, okay. What drove me to drink?” “That’s not relevant. Just look pained when anyone offers you a beer.”

• Three episodes in, the investigation seems to be going pretty well. Bit concerned this will leave it susceptible to artificial, unlikely obstacles inserted to spin things out. Prison Break was particularly bad at this (“oh no, I’ve sustained third degree burns to the part of my breakout-plan tattoo that we need next – and I can’t remember what it said!!!”).

• I know they’ve said they’ll wrap things up this season, but let’s be realistic – if it’s a hit, there will be more seasons. Which means more flashforwards. Which means I suspect this season, and future ones, will end with them solving the case only to find it part of a much wider conspiracy. At some point someone will probably say “it’s just like peeling an onion”. Beyond one season, this might get a bit tiring.
