It is because the Lost comic-con event caters to the overly obsessive part of the Lost fanbase, and they were pushing their last online Lost game, which exists for the overly obsessed fans as a way to build up interest in the show between seasons. They always tie these things in with comic-con. The last game was something about becoming a recruit for a revival of the Dharma Initiative, so they set up a booth at comic-con to promote it. I guess you could register at the booth or online. They have done the same kind of thing between seasons 2 and 3 and between 3 and 4. It is always cheesy and pretty lame, but some of these people really get into analyzing every little aspect of show and they really eat this crap up.
The only part of it that is worth while would be cool things that come out of it like the clip of Faraday filming the orientation video guy, or last years Orchid orientation video out takes. In the end, the framing of the video is something you can just cut out.
And yeah, so far this season has been off to a great start. Was finally able to sit down and watch these two new episodes a few hours ago. I hope they keep it at this quality and don't drop the ball for the sake of cheap tricks like the poison gas station episode last season, where they spend the whole episode making you think Dan and C.S. Lewis are evil, then flip it at the end and make it turn out that it was just a big misunderstanding and they only had to knock out Kate and leave her with a bleeding head wound and a possible concussion lying unconscious in the middle of a dangerous jungle because it would have taken them too long to explain to her and convince her that the evil men who kidnap small children and pregnant women, and lock people in animal cages, and strap kids to chairs to brain wash them (in other words, some people Kate already knew were pretty f-ed up and able to do great evil) built a toxic gas releasing station solely for the purpose of killing everyone on the island in the event of an emergency that Dan and Charlotte felt the need to disable. I hate episodes like that. Oh, or the episode where Sun has her baby and they try to make us think Jinn is on his way to see her, only to cheaply reveal at the end of the episode that he died on the island and we were watching two separate sets of flashbacks.
We have been bombarded with four years of mysteries, many that have been revealed, but plenty of others that it feels like the writers have pretty much forgotten about (I want to know who the hell Monton is and how the hell he lost his fricken arm! Monton and his arm are pretty much the whole reason I still watch the show, I have been waiting anxiously since the end of season two to learn more about ol' Monton). Barely thirty some episodes left in the series, slightly more than your traditional 20+ episode season, and they have a lot of ground to cover. Really hate to see them waste it on cheap tricks and meaningless episodes they do nothing to push the story along. Here is hoping season five doesn't feel the need to pull crap like that. (At least Frogert was done away with quick and painlessly without the need of another Nikki and Paulo incident).
