This Giant-man story seems a lot more like a DC story to me than a Marvel one.
The cover is decidedly in DC's "What on Earth is going on here? Buy the book and find out"-style than Marvel's "This scene is REALLY cool, buy the book to see it play out"-style, the plot about a crook stumbling over the hero's costume and taking his role is something I'm sure DC has done many times, and the plant subplot is exactly the kind of stuff I'd expect to see over there.
Really weird. Not bad (though hardly good either), but very very unlike anything else we've seen from Marvel so far.

Burgos' style lent itself well to over-the-top action stories with tons of explosions and a fast pace. I don't think Giant-Man was the best strip for him to do, but Marvel didn't really have anything of that type either, so I'm not sure where I'd rather have him. Maybe on Hulk or X-men?

Out yonder, under the shining vault, among men the saying goes: 'Man, be thyself!'
At home here with us, 'mid the tribe of the trolls, the saying goes: 'Troll, to thyself be-enough!'
