Following on from the post below on lost series 2. It seems that it will not stop there. Rumour has it that the actors have signed up for 3 more series. Its only a rumour but has been stated by alot of people. If this is the case i think it wil ruin it. It was already enough secrecy in series one to keep you hanging on, imaging another 3 or 4 series of wanting to know.
I have heard they've signed up for 8 series - i don't think it'll ever run for that long but i guess they want the option! I for one hope it lasts for a couple more series' yet. I think they'll reveal the secrets but bring more in as the whole story carries on.
It would definitely be a shame if it ended after Series 2. Another one after that would be good but yeah, too many and people will lose interest, especially as there's 25 episodes in each series.
