I also liked it, but it doesn't replace the original series. Its just an alternate retelling of the story.

To me, its the same as the Super Dimension Fortress Macross tv series, and the Macross Do You Remember Love? movie. Neither is better or replaces the other, they are just alternate retellings of the same story. In the same way that two different war veterans might describe the same battle differently, even though the same major story elements occur in each.
