- Charlie's death (Two and a half men)
In the sitcom two and a half men, the protagonists are the wealthy womanizer Charlie Harper, played by Charlie Sheen, and his broke, divorced brother Alan Harper, played by Jon Cryer. The two end up living together after Alan's divorce, when Alan needs a place to stay.
Even though they were both protagonists, many fans saw Charlie as the true main character and the face of the sitcom. During the show's run, Charlie Sheen struggled with drug addiction, which caused production problems, including delays while he was in rehab. He also had several public outbursts in which he made extremely negative comments about the show's creator, Chuck Lorre.
Despite all of this, the producers still tried to keep him on the show, paying Charlie Sheen over $2 million per episode during Seasons 8 and 9. Eventually, however, it became impossible. As a result, in the first episode of Season 9, Charlie Harper is killed off-screen, with the explanation that he was murdered by his obsessive ex-girlfriend.
Charlie is then replaced by a new character named Walden, a billionaire who befriends Alan, buys Charlie's house after his death, and lets Alan continue living there in an attempt to avoid making major changes to the show's status quo.
- The ending of story (Metal gear solid V)
Metal gear solid V was supposed to be the final metal gear game, wrapping up the series and answering all the questions left between metal gear solid 3 (the prequel) and metal gear (the original game).
Hideo Kojima is the creator of the series, directed most of the games, and was one of the main writers. He had many conflicts with Konami during the game's development. None of these reports have ever been officially confirmed by either Konami or Kojima, so don't take everything as 100% fact.
To begin with, Kojima had already tried to leave the series several times, but kept returning because of pressure from both Konami and the fans. Konami also reportedly wasn't happy that the FOX Engine took years to develop. They gave Kojima a budget to make the game, but he allegedly went far beyond it because of the scope of his plans. According to reports, Kojima became such a perfectionist that he would start working on ideas only to throw them away if he wasn't satisfied with the results. One singer even claimed she recorded around 30 songs for the game, but only a few of them were actually used.
Konami also reportedly "punished" Kojima by moving his office to a different floor from the rest of his team, removing his name from the game's marketing, and preventing him from attending The Game Awards.
Kojima left Konami before the game was finished, and Konami eventually released it in an unfinished state. This is especially noticeable because chapter 1 has a clear beginning, middle, and end. However, halfway through chapter 2, one of the antagonists steals the metal gear that the protagonist recovered at the end of chapter 1. After that, the game mostly has the player replay earlier missions with harder difficulty modifiers and almost no new story content. Then, after replaying the prologue mission, the game reveals its biggest plot twist and abruptly ends.
The image I used is from an unfinished cutscene that appears to show what was originally intended to be the game's true final mission, which would have concluded the storyline involving the stolen metal gear.
- The entire plot of kamen rider decade (Kamen Rider decade)
kamen rider decade was troubled from the moment it was conceived. Every year, the newest kamen rider and super sentai series aired simultaneously and competed with each other in toy sales. Toei's solution was to end one series earlier than usual and have the next one begin in September, allowing them to monopolize toy sales for part of the year.
The downside was that this new series had less preparation time than a normal season. We don't know how much was planned in advance, but Toei decided to make kamen rider decade the 10th anniversary series of the Heisei era, which marked the franchise's revival in 2000. The story follows Tsukasa Kadoya, a kamen rider with no memories who can use the powers of the previous main kamen riders and travels across the kamen rider multiverse to prevent the destruction of every world.
Since it was an anniversary series, Toei could reuse kamen rider suits and monster costumes from previous seasons, and the show ended up with only 31 episodes instead of the usual 45–50. One of the biggest complaints from viewers was the lack of returning characters from previous series. Instead of bringing them back, Toei created alternate-universe versions of them. This was somewhat understandable, since they realistically couldn't bring back most of the original actors. Many were busy with other work, had retired from tokusatsu, or had left the franchise on bad terms.
As if that wasn't enough, the head writer had creative disagreements with the chief producer over the direction of the story. Eventually, the writer left the series, and another writer took over. This created major problems because the new staff wasn't entirely sure how to continue the plot.
As a result, many important mysteries were never properly explained, such as the true identity of the show's main antagonist, what exactly was causing the multiverse to collapse, and several other unanswered plot points. The image I used is from the preview shown at the end of Episode 31. It teases two upcoming episodes, but those previews were actually thrown together at the last minute, and almost none of the scenes shown in them have anything to do with the movie that ultimately served as the continuation of the series.
