REUSED AND RECYCLED
Okay, I'm going to complain a little bit more. "Captain Scarlett" felt fairly fresh, with an all-new cast, a totally unique vehicle, and tons of new enemies and locations. 'Mr. Torgue,' on the other hand, feels painfully familiar for most of its duration. The environments aren't as interesting as 'Captain Scarlett''s desertscapes, feeling mostly like rehashes of existing location themes.
Beyond that, many of the characters (besides Mr. Torgue himself, who's an instant classic as far as I'm concerned) are far too similar to existing ones. Gearbox seems to have reused several character models—the obese biker boss I mentioned earlier looks suspiciously like Scooter's fat sister, Ellie—and while there's nothing wrong with that, it's occasionally a tad too obvious. A few of the characters, like number one badass Piston, even look like bizarro doppelgangers of player characters (Salvador, in this instance).
In addition, several character—Moxxi, Tannis, Tiny Tina—reappear from the main campaign, and while I was happy to see them again, I'd have rather been treated to some more interesting new personas.
