: I disagree with you here. Subplots can make an episode more interesting. In fact, circumstances could easily lead to a divided cast.

No disagreement here. Subplots CAN make an episode more interesting. I only take issue with the way that these subplots were handled in some (not all) episodes. For example, the Challenger/Summerlee raptor escape subplot was just a meager excuse to have these two on-screen at all. Usually at least one storyline suffers from the limited time available.

: : 1. Introduce some original TLW coherence and continuity. Create a world in itself with recurring original tribes and characters, get rid of that wildly peculiar mixture of cultures from different places and times we saw in season one (Vikings, Egyptians...... you get the picture).

: In mountainous jungles by an inland sea at the middle of the Lost World are extensive ruins like those at Tikal or Ankor. A magnificant culture built them many years ago. Now they are peopled by the decendents of the builders, a primitive, but beautiful people, who do not speak English. All initially view the expeditions with suspicion, some want to use them, others want to learn from them. Both expeditions try to gain them as allies. There are no other cultures.

I like the Angkor idea. As long as it is an original creation, and not just another ancient culture rip-off like we saw in season one. The second expedition idea also has potential.

: : 2. Introduce a recurring nemesis for the group. This would give the show more direction and depth. That doesn't exclude a wide variety of different villains, of course.

: How about one of Marguerite's former associates ( the one that hired the assassin )? How about her former lover driven by hate, but actually still loving her? She's his obcession. How about a tribal shamen? If it wasn't Krux's former lover, I'd recommend a screwd character, calculating, the kind that sets interesting traps. The Cardinal behind the throne.

I think it's important to have a larger-than-life character as the recurring nemesis. Not just your next door villain. This person needs to have the physical and intellectual capabilities to pose a real threat to the group.
