I am going to continue my list of continuity glitches along with additional editorial screw-ups that should never have taken place.
2) No matter what the continuity is, there will still have been a pact made with "the devil," which is entirely amoral and sends a terrible image to children, upsets parents, and does irreparable damage to Spider-man as a property. Editorially speaking, this was a nightmarish, colossal mistake on the part of Quesada, and he should be held accountable for this clear lapse in judgement. Arguments that claim Mephisto is not really the devil have no merit. Renaissance literature and post-biblical Christian texts have referred to the name Mephistopheles for hundreds of years, cementing the name in the public consciousness as another name for the devil. Making a deal with the devil is never acceptable, no matter what the terms or intentions are.
3) Harry being brought back from the dead with no explanation is simply ludicrous. His presence in the books has contributed little more than turning Peter Parker into a club kid who mooches money from his friends while simultaneously hitting on their girlfriends. It also makes the books less like the major movie franchise, wherein Harry JUST DIED. This makes the current continuity less accessible to a clear majority of potential readers.
4) Civil War was a MASSIVE success, especially issue #2, wherein Spider-man unmasks to the world. The decision was applauded by many as a daring and exciting move, and the book far outsold Brand New Day after similar amounts of national media attention. With the undeniable popularity of Civil War, and the ongoing success of Amazing Spider-man in its aftermath as well as the continued sales of the Civil War trade paperback, retconning the most successful story in years almost immediately has had a negative impact on sales that cannot be blamed on the economy. It has also destroyed Marvel's credibility. The consequences of Civil War were never fully explored and Marvel went for the cheap way out, instead of exploring all the amazing story possibilities that were sure to come.
5) Gratuitous depictions of controversial images for the sole purpose of shock value gags have done serious harm to the recent books. Parents have complained about a number of the full-page splash interiors. The Spider-mugger pointing a gun at the reader confused many children, who were unable to easily comprehend the picture in the manner that mature readers were able to interpret it. Questions ranged from "why is Spider-man holding a gun?" to "is Spider-man a bad guy now?" To have this image (which would be banned from most cable networks) emblazoned on page two one issue after Spider-man made a deal with the devil showed poor judgement on the part of the editors. Other images throughout Brand New Day have also been inappropriate. The numerous images of Peter Parker/Spider-man performing CPR should have been done more tastefully, not tilted sideways for a cheap gag. It was funny to older readers, again, but not appropriate for an "all ages" book. The frontal image of Freak clearly using illegal drugs was also not executed well or clearly enough. Images like that need to be explained to "all ages" audiences, in order to enforce the message that drugs are bad. The book was written so poorly as to possibly be misinterpretted to believe that using drugs will make you invincible and give you super powers. Past stories that involved illegal drug use were handled carefully and responsibly. this one was not, and in fact was rather gratuitous. I cannot read these books to my daughter, nor can most parents do so for their kids. They should not be rated ALL AGES. If the intent of the retcon was to "de-age" Spider-man in order to appeal more to a younger audience, the attempt has failed miserably. The book is less able to reach its target audience now than it has at any point in history.
6) Peter Parker, when he thought he was a clone, beat his wife. This was such a key point, in fact, in people's subconscious, that the scene even worked its way into the recent movie. This decision was not Quesada's fault, but rather than retcon it, he instead allowed the exact same thing to happen in the new books, where Spider-man punches Jackpot in the face for a cheap, and very droll, shock gag. Since Jackpot is widely believed to be, and not-so-subtly hinted at as being Mary Jane, this image is all the more detrimental to Spider-man's character. He is now the type of man that brutally assaults innocent women. This should not have been allowed.
7) Spider-man Vs. Wolverine... did it happen? It seems that if you are going to perform a massive retcon, you would also attempt to try and retcon the story that made Spider-man a killer. If not, then it is clear that Wolverine and probably Daredevil, as well as many others know Spider-man's secret identity even post-retcon. Either way, if Spider-man vs. Wolverine is still canon, then I have a problem with Spider-man being a killer, even if the story was well done, which it was.
8) Convoluted continuity that muddles readers' memories of past stories destroy the suspension of disbelief that is required to make new stories engaging and immersive. While some are able to blindly follow and accept these premises, many others have tremendous difficulty in doing so. Doing a poor job of establishing a premise limits the potential readership. Even when past stories are said to have all still taken place with a find/replace on wife to girlfriend, certain stories do not work, such as the ill-conceived and ill-fated pregnancy that Quesada has said didn't happen. If that didn't happen, what was the butterfly effect? If Mary Jane wasn't pregnant all those months, what was she doing? Did her career take off?
9) Constant derisive references in the stories, written as in-jokes that demean the fans and insult their intelligence have no place in Spider-man. "Tongue-in-cheek" jokes have mutated into "sticking-your-tongue-out" at fans, much of it taking place right there in the books as either editorial notes or situational references to real events or statements. The fourth wall has been shattered in many cases, and it feels like the writers and editors are speaking directly to the reader as though the story itself were a forum or soapbox for them. This is an intolerably poor creative habit that needs to be stopped at once.
10) Clone Saga. If it is still in continuity after all this, I demand to know why.
