well, i dont support the WHOLE jlu. it was a cool episode of batman beyond, but, im happy with it just being contained to an episode.
as for the "war hawk" character... yeah, i agree, he's nothing incredible. however, i think just the fact that they attempted to update an outdated character means its an improvement. hawkman, in my mind, IS one of those kinda characters that needs to be updated, or at least streamlined to fit in today's genres. he's just too hokey.
