I had the same problem with BL2 and BL3, and 3 compounded it with the truly screeching villains. The villain in Wonderlands is played by Will Arnett and he’s, well, wonderful.
You can tell Gearbox started Wonderlands during the pandemic intending it to be another premiere DLC for BL3 just like they did for BL2, but the pandemic kept stretching on and they were clearly enjoying themselves, so they made a full game. The fantastic environments are the opposite of Borderlands; an entire town raised up on a beanstalk, a fantasy city, the bottom of a recently drained ocean (preceded by one of the best surprises ever), etc.
Unfortunately that explains the crappy DLCs too. Don’t buy the ultimate edition or the season pass separately.
