season2 was interesting... but i dunno if i'll be following it as closely the next season... or that it'll be renewed.

I enjoyed it. Don't think it is superb, but definitely better than a lot of other stuff that is showing.

Quick question. Is the scraggly guy at the end by the lake someone who died previously? ;)

Spoiler Notice!
 

yes - it is someone who died previously

i think the season finale was trying to imply that all this time in season1&2, the 4400's abilities were actually inhibited. now that they don't have the suppressant, they can actually work their "miracles" to bring the future to the present.
