I LOVED the movie Powder! I empathized strongly with him.
You pointed out that many (if not most) people can find themselves within the description of an Indigo adult. This concerns me as well... can Indigo adults really be a small group of people if most people fit the description? Maybe we don't have a complete description yet. I dunno, but I do have a healthy level of skepticism. I fit the description almost completely, but I'm not quick to buy into things... I usually require further investigation.
Whether or not I'm an Indigo adult, I would like to get to know other adults who are similar to me. I am 29 and live on the East coast.
