THE PROBLEM IS NOT THAT THEY REMADE IT
The problem is that they remade it without bringing something new to the story, they just retold the original back in it's original setting.
In film practically every story that could be done has been done, the only new thing you can bring to an idea is prospective, and the problem with this movie is that it does not show us the story from any sort of new angle.
When you think were Baz Lurman took the story in 96, and everything that has happened since then, 911, a black president, the financial crash, there was tons of of modern material to help give this film a modern up to date fresh look and feel, whilst staying true to the story. But instead they decided to be less forward thickening then an adaptation 16 (yes I said sixteen) years earlier, how does that work out.
