In summary, it went into the effects that the original movie had, and why it had such a large impact as it did, with the primary reasons being, that it did so many things first and set many new precedents that would get adopted my the movie industry and Disney itself later.
So when you add on top of that the remake, there is a strong potential for the remake, even if done really well, of being underwhelming when it will come out.
It brings to mind my family's reaction when I told them about the remake being made: Yet Another Great Movie Ruined by Modern Hollywood. Are they right to not be excited about the remake? Or are they jumping to conclusions?
