If Blomkamp has permission to erase canon, it points to an entirely different trend. Not one that involves "going back to a previous point", but one that appears to be in full swing in Hollywood right now.
Although, at the risk of showing my age, the whole concern with "canon" is pretty much a new trend in itself. Prior to the eighties, movie series tended to play fast and loose with continuity in ways that would make modern fans' heads explode.
Getting back to the MUMMY movies, at one point an entire town migrates from New England to the Deep South without explanation!
