User blog comment:Wikiatastic/Bloom is not a Mary Sue/@comment-29197449-20190518014803

It's probably because, in a lot of instances, the plot bends itself around her when it doesn't have to. It's one thing for her to be a plot-centered character, which isn't bad, but it's another thing when the plot puts her in the focus for nearly everything as if she's the only one that matters, which is what a lot of people felt S5 and S6 were doing.

I wouldn't say she's a Mary Sue but the show often treats her like she's the only one who the audience is even watching the show for. I only remember that being a big issue in S5 and most of 6, so, in the grand scheme of things, it's not a lot.
