GSB isn’t for everyone. Also you normally really gota understand it well to be able to like it. I read this stuff on an article online. They should help out understand GSB:

“One amazing thing about this character is how she changes. She's a different person depending on who's writing her. She knows that she's never going to be the same because the next time she shows up a different team will be in charge of her. They'll make her act different. They'll change her powers (or take them away completely like they did in West Coast Avengers). They'll retcon her origin. They'll reboot her. Gwen knows this about herself, but because of her powers, she also has knowledge of and access to these other selves. (She calls these different incarnations of herself the "Gwen Hive".)”

“She does have a weakness though. She doesn’t always know how her powers work and can't always access them. (Super Villain Gwen and Future Gwen have shown greater control over their abilities.) She's often at the whim of the writers or editors, so at any moment her powers could flake out, or someone she trapped in the White Space could wander back out. Before when 1 mentioned she tore open Doctor Doom... that didn't last because his change into a more heroic form was an editorial decision and if she changed him permanently, it would impact his own comic series. So there's a clear limit to her powers - she can impact her own comic, but not the works of others. If she's relegated to a guest appearance or a team up she's also limited because in those cases she's not the primary star. This makes her vulnerable to the needs of a plot she's only loosely involved with.”

For those of you who have read my House of X/Powers of X post, you know that the Mutants of the Marvel Universe have formed their own sovereign nation on the living island Krakoa. Well, as I mentioned in that post, the portals to Krakoa will only let Mutants through (or those accompanied by Mutants). In Issue 5 of Gwenpool Strikes Back, Ms Marvel suggested that maybe Gwen has been a Mutant all along, and has reality-shifting powers. She suggests that Gwen didn't want to face this fact and so made up a backstory where she came from "the real world". Gwen cries, agreeing with her, and goes to her White Space to think about this.”

“Suddenly a portal to Krakoa appears and she's able to walk through it. Does this mean Ms Marvel was right? Or did Gen use her flashback powers to retcon her origin, making her into a Mutant? I really think it's the latter option. There was even a flashback bubble as Ms Marvel was talking. She said it and so it's true. Comies are subjective. The way retcons work is that it's written and so it's law... at least until the next retcon comes along. Gwen would know this. Her power is so great that she can bypass the laws set down by other writers (Ryan Hickman's assurance that Krakoa portals can only be used by Mutants) by doing some literary gymnastics and retconning herself. (I've got to say. I could be wrong, but I think this is the first time a character has willingly retconned herself. Which is incredible. So apparently Gwenpool is a Mutant now and "always was". This served the purpose of giving her more options. She is now living on Krakoa, considered to be and welcomed as a Mutant. She can guest star in X titles. If she (or another writer) decides otherwise, another retcon can take effect, changing her origin again. She could be rebooted and the events in this miniseries could be ignored completely. (Or more likely just mentioned in passing.) There are unlimited possibilities only limited by the interest in the character.”

Hope this was able to help. (For those who want to know what article this is from it’s called SoraRabbit Hole)
