The actual origin story isn't that important to me, certainly not at this point. If they want to do a secret files type issue with it, that would be okay. I would really like to see something other than "3 kids save billionaire" - but their funding has to come from somewhere... maybe one of the early group is very very rich? They seem to have been together for several years (2 years?), so there's a lot to backfill.
It's a good story telling technique to reveal information about the characters gradually, either in snippets (as we've had for most of the characters so far) or more detail (as for Lyle and Lu). Old-time fans have the added interest of wondering/learning how much the new versions differ from the old characters, how much history will repeat itself, and with what twists. Keeps the interest level very high for me. It's all unfolding.
