I don't really have any strong opinions either way. Borderlands doesn't seem like the universe most worthy of expanding, but I doubt this will have the exact same tone as the games or the same people working on it.
It's not a great universe, but I like a lot of how it's kinda NOT explained. Like the one town in Borderlands 2 where you help them with a disease and then put up a shield and the bar is near it. Like you only get little bits and pieces of their existence and there's always this quirky air of mystery about everything in the world. Which is why I never had complaints about the first game or the environments (especially since some of the first game reminded me of driving in the American Southwest) because it's all kinda picking at my brain about the areas and things in them: why are they here?
Plus the stuff like the Tannis logs and so on is right up my alley.
The comics kinda went the wrong way by trying to explain every characters backstory and repeating events of the game instead of going with new characters in the world like this is doing. Though I did kinda like the framing device of how the original four vault hunters wind up by circumstance on Marcus' bus for the start of that game and his tale telling them of The Vault. Though that's another "less is more" thing since it kinda implies, like the end of the first game with the reveal of the Angel that there's bigger forces at play, but the series is almost decidedly refusing to do much more than sketch them out.
EDIT: Actually, what it kinda reminds me of is the start of Fables (the comic, not the game) where everything hints around The Adversary but the comic gives you basically no information on him other than he's bad for like 40-50 issues.
