Civil War: Front Line was the best tie-in Civil War had, and even superior to the main series. It explored the impact of the Superhuman Registration Act on the smaller corners of the Marvel universe, and explored the central conflict in a much deeper way than anywhere else. So it makes sense Marvel would want to resurrect the title as a companion piece to World War Hulk, right?
Not so much. If there's a point to this story, it's that World War Hulk didn't affect the Marvel universe all that much, unless for people owning property in New York. There's a few attempts at poignancy: Ben Urich realizing the alien invaders had an easy conquest because the people of earth are about as perverted as them, Sally Floyd flipping Daredevil the finger for every superhero who just makes the lives of the common man more difficult, but that's about it.
Instead we get the story of how Front Line becomes a worthy competitor of the Daily Bugle, which - even in the presence of J. Jonah Jameson - is void of any drama, as is Sally's tacked-on struggle with alcoholism. The second story has Danny Granville and Korg investigating a murder, and again there are stabs at the moral philosophy Paul Jenkins is known for, but even he struggles to find significance in a smash-fest that really only mattered to a handful of characters, none of whom are in this book. The less said about the cartoon-strip War Is Heck, the better.
In the end Paul Jenkins and his team did what they could with what they'd been given to work with. It's not much but at least Front Line gave more class to the World War Hulk event at times than most of the other tie-ins combined.
