Lots of cool visual effects and technical complexities. It turns out the tech complexities are mostly irrelevant. In fact the entire dreaming and reality part of the story is pretty much pointless. It's a basically a sci fi twist on some really old themes. The sci fi part is really fun but those old themes have been conquered by better men with better skills both in director's chair and in front of the camera. I would hazard a guess that beyond some simple nostalgia in a few years no one will remember this one or care about it. It won't hold up. You can boil the entire movie down to father issues and regret issues and both have been done better and more intelligently. I know I'm late to the party and I'm clearly old because I don't find the hype accurate but I figured I would weigh in anyway
