Hi Margot,

welcome to the board. :)
You've definitely seen only first season episodes, since they haven't even started filming the second season yet.

: It's an interesting action/adventure story - and that plateau does appear to go on forever!!. Maybe it's in its own dimensional plane - that's why no one ever seems to get out and why so many odd and varied cultures are found inside of it.

Its own dimesional plane......Mmmmmh. As far as I remember we haven't had that particular explanation on this board before. Please don't give the TLW writers any more excuses for not introducing some original Lost World continuity and coherence next season. ;))

Have fun!
