"Lore most fans love" is a pretty subjective term. It boils down to not every fan is going to like what they see.
There's a difference between introducing something new and butchering lore that won't go unnoticed. If someone decided to make a movie that completely cuts P2 from the timeline, a good number of people wouldn't be happy. If a movie cut out an obscure comic, then I don't think too many people would care. However, that is subjective. How do I know that a lot of people enjoy this comic or hated that movie? How do I know what fans really want when you see a variety of conflicting opinions daily?
