"When Hollywood releases movies, clashes often arise between studios and directors, leading to cut scenes and alternate endings. These alternate cuts intrigue fans eager to explore the 'what-ifs' of their favorite stories, some aligning more with the creators' original vision. In certain films, endings even change based on the market—European audiences tend to embrace sadder conclusions, while American viewers often prefer optimistic ones, leading to multiple versions. Alternate endings evoke mixed reactions from fans, ranging from criticism to disappointment when they aren't included in the final cut. Some may seem overly bleak or artificially happy, while others can undermine sequels.
