I will never understand the attitude that a new movie can ruin an older movie.
I experienced this issue with the Lord of the Rings trilogy and the Hobbit trilogy. For example, in ‘Fellowship of the Ring’ Saruman says to Gandalf:
You know of what I speak, Gandalf: a great Eye, lidless, wreathed in flame.
This sentence (and the scene) was perfectly fine before i saw the Hobbit trilogy.
Then in ‘Desolation of Smaug’, Gandalf sees Sauron when he changes his appearance to the lidless, fiery eye. That sentence in ‘Fellowship’ is now (retcon-wise) a backward reference to the scene in ‘Desolation’. Everytime i see now ‘Fellowship of the Ring’ (my favourite LOTR movie btw), i will be remembered that there is this other ‘mediocre’ Middleearth trilogy i don’t really like. It doesn’t ruin ‘Fellowship’, but it annoys me being reminded about the Hobbit trilogy in that scene.
I fear something could happen when i see the Han Solo movie. What will happen to my memories about to Han’s and Landos first meeting in ESB? Can i still enjoy the scene in Cloud City or will i be reminded about stupid stuff from the Han Solo movie? You know, we will see how Lando will lose the Falcon fair & square to Han or something like that. I don’t want to know how that happened.
