The total running time of the remake was more than the original movie, yet somehow said a lot less. Aside from the visuals, the movie was embarassingly mediocre.
Spoiler: In the original the antagonist is basically the singularity, a new form of life born from code. In the remake? Oh, her ex boyfriend.
When the first movie came out people were complaining that it is not the manga. I'm pretty sure if they'd made a 1:1 copy of the 1995 movie, the same people would complain about that.
There is no way to please everybody. People will find reasons if they feel they need them.
Because of that, I find that harsh and kind of orthodox criticism quite over the top.
(Yes I understand all the reasons commercially why it was remade, no those don't change my opinions on the matter.)
