Nellie would be bad enough as a side character, but as The Office floundered in the wake of Carell's absence, perhaps the worst part about her is how prominently and frequently she was featured on the show. All of a sudden, Nellie became one of the show's biggest characters — spending a seemingly enormous amount of time on screen to the point where fans were begging to have her written out of the series entirely.
It's not Tate's fault that her character was so deeply underwritten, but it seems that showrunner Greg Daniels and his team were somewhat oblivious to how much everybody hated Nellie. Even though Michael certainly could be unpleasant throughout his tenure as Regional Manager, he had some redeeming qualities. Nellie, on the other hand, had basically none — making it almost impossible for viewers to root for her in any real way.
