Iv gotta wholeheartedly agree with Lod Haseo concerning the fan edit idea of preserving the Kylo twist. It just isn’t worth it. All the things you guys would cut are things that bring meaning to the film and cutting them to preserve a twist just doesn’t make sense.
The scene with Snoke revealing Kylos lineage is incredibly important. It establishes the conflict within Kylo and also shows Snoke putting pressure on Kylo to not give in to the light.
The “Grandfather” line lets the audience know that Kylo doesn’t know or decides to ignore the true legacy of Darth Vader.
These are all reasons it simply doesn’t make sense to preserve a twist like this whilst sacrificing so many story elements and additions.
