So three years ago, ABC scored a major hit with the mysterious tone and inter-wound plots of "Lost." After two years of being the breakout hit in this genre, last year the other networks responded with "Heroes" (NBC) and "Jericho" (CBS), which followed very similar formulas. Last season, I really viewed these three shows as three leaves on the same branch of the television tree; are there leaves I'm missing? I know several of this year's shows try and ride the wave: certainly "Journeyman." Anything else? I'm not just talking crazy, fantasy dramas - I'm talking shows that encourage fans to tie clues together via websites, that incorporate vast timelines that flashback between character's lives, that end on mini-cliffhangers each episode and giant cliff-hangers each season, that have underlying questions (Where's the island? Where did these powers come from? Who dropped the bomb?) that aren't answers for months, if not years, if ever, etc.
