10-15 years ago you could make a movie with great cgi and no story, and the audience would love it. Today, great cgi is a minimum requirement, it's taken for granted. It's nothing special. That's why you better have a damn good story, great graphics are not awe-inspiring anymore.

Sadly, they forgot to bring the good story in this film. It's just a rehash of Avatar 1 + irrelevant teenage stuff + silly American hero worship + your standard war film. They've created something completely generic, the story has been told a thousand times, and better.

It's sad, really. The Avatar 1 universe is wonderful, they could have created something truly unique - or maybe they should have left it alone.
