JJ had almost no relationship with Lost and Fringe beyond helping to get their pilots made. I do wish he would not be attributed with so many enjoyable shows with which he largely had a passing acquaintance.Cameron is great. My vote for creativity goes to JJ Abrams though. Overall, Cameron is more accomplished but Abrams can really keep you on the edge of your seat. Taking on Star Trek was an extremely tough challenge and IMO he pulled it off great and opened the door to so many possibilities for future movies. Fringe and Lost are in a league of their own as far as tv shows go. (if your into those kinda shows).
