Perhaps you misunderstand me. I'm not criticising content here. I'm talking about the plot. The plot was unrealistic in the sense that they do what they want to do, and they don't portray events unfolding the way they would actually unfold if they were real. The way realism in fantasy/sci-fi/fiction works is you portray your fictional component as close as you can to how it would operate if it existed. So, if there was a space fleet, and academies of mecha pilots, would they be teenagers, or would they be adults? If the two best pilots in the country were selected to go to the war fleet, would it be likely that the two best pilots in the country be teenagers, or adults? If you look at the closest example in real life, it would be fighter pilots. Teenagers at cadet camp train in flight simulators, but the professional pilots in the air force who actually are Ace pilots, are all adults. A teenager might excel at something like a video game, over an adult, maybe ten years ago. Nowadays though that isn't the case anymore. Adults play video games and over 90% of the best players in the world are adults who have been playing since they were teenagers. I'm not saying that the movie should have been as realistic as reality. But it was very far from portraying it's subject matter in a believable way. Which is fine. It's not that serious of a movie (or series technically). But I consider it a flaw unless it's done in a very intentional way, and I didn't get that impression. To me it seemed like they wanted to do what they wanted to do. There was no deeper meaning to it being unrealistic. It didn't carry some inner criticism or satire that I could detect in the way it portrayed things unrealistically.
See, the way I look at it, the content is that there are two teenagers who are the best mech a pilots in Japan, and they study at an high-school level mecha academy. That's fine. But how that content is presented is where realism in a qualitative sense separate from the content itself comes into play. There should also have been adult academies, and they should have demonstrated why these teenagers were better than adult pilots. Instead they took their premise completely for granted. Don't get me wrong. I'm not saying the anime was bad at all. It was good. I'm just saying that those things hold it back, in my opinion, from being exceptional.
