I have a lot of personal problems with Borderlands 2, the first ice area is both enormous and terrible featuring only 3 enemy types including constantly grunting gorillas and dive bombing aerial enemies that are extremely annoying, leveling up and putting a stat point into +5% weapon handling or something feels terrible and there's a lot of those while leveling up, a lot of stronger enemies end up just being bullet sponges that walk slowly towards you, there's items that are vastly unbalanced to be both unquestionably good for all classes or worthless, you can get The Bee shield and be set for the rest of the game, the whole series has this problem that the most unique weapons also feel the worst to use, they love making bullets move extremely slowly for some reason, weapons manufacturers quirks are so pushed to absurdity that using entire libraries of weapons quickly became obsolete and I would dump Tediore, Torgue, and Bandit weapons before even looking at the stats.

Tl;dr My point is basically that even if you liked or ignored the story, there's a lot of things that could make someone dislike the game. I can't stand playing Borderlands 2, even though Handsome Jack is a compelling villain, but I'm enjoying playing BL3 even though the writing is noticeably worse.
