It's more of the same. It's a direct sequel to MJP anime, If you just want more mecha action - this movie provides it. Genetic Awakening doesn't put an exclamation mark for the ongoing conflict. We have left over aliens to mop up, let's do it. If you feel like there are some plot threads that the anime left hanging, they are not elaborated in the movie. Izuru is out of commission, that puts Asagi in the spotlight, which is cool. Unlike something like Martian Successor Nadesico: The Prince of Darkness, the humor is still there and still the same. Majestic Prince was ultimately about instincts vs altruism,the movie doesn't question it, reinforce or just say anything new about it.
On its own, Genetic Awakening is great. In context of the series, it has no reason to exist.
