I think, to be fair, a lot of US television shows in the wake of 9/11, spent some time devoting subsequent storylines that reflected events - (er did a storyline about a bio-hazard lockdown for example) - and one could argue that 24 was more than a little influenced by it as well, going so far as to define itself as a series about a character who while acting to defend one system often completely disregarded that same system in favour of his own morality and decisions.
Star Trek: Enterprise wasn't doing anything really that wasn't being done elsewhere in terms of reflecting, irrespective of whether one thinks the storyline itself was well done or not.
