The game has some seriously messy art direction as well. Contrast and color are all over the place. No focal points. No distinction between forground and background, playable/non-playable space, etc. Lots of effort being put into really stupid ideas as well, like their "menus are in the world now!" and "enemies can climb walls to get to you!" (can the player climb walls? no? why not? A: bad design).
How much effort or development time did they put into strapping that stupid midget to the bosses shield like that? Probably not enough to justify the one-time chuckle it gets you.
I think things are a mess at Gearbox. They don't look like they have any good leadership in the areas that count right now. It looks like the product of a team of people pushing things together willy-nilly with no ultimate vision or direction.
The first game was a total patchwork itself, only barely held together by a semi-interesting random-drop system. Since they've removed that sole interesting mechanic, this is going to be a completely ignorable release.
