How could this movie be positively reviewed so often?

Rating: 2/10 (30 March 2018)

I really don't know what the critics saw or if they maybe received some bribing but what the hell??? I really couldn't wait to see this movie finally and it definitely has some nice elements, like that you don't see the Germans the whole movie except of the last scene, but there were sooooo many unrealistic scenes and sorry in a movie like this I want to have full realism. So what the hell is going on with the ammunition of the Spitfires, they would have been out of ammo right after the first fight and here they fight forever, also how long can this Spitfire glide in the final scene and WHAT THE HELL, why is he landing the Spitfire to then burn it and to be captured when he could have easily bailed above the evacuation zone. And what kind of ship is this, which can still swim even it is filled with holes, water and lots of humans and boy all the flight scenes, in one scene the Heinkels are already even too close to bomb and we still see several minutes flying of the Spitfires until they are in the right position and the Heinkel probably just hovered on the same position. There are sooo many unrealistic and stupid things going on in the movie I really don't get how anyone could give it a positive rating. Also the whole story around the boy who died....are you kidding me? He dies from the fall? I mean of course there are stupid ways how this could happen, but what are the chances and then the newspaper? How did he rescue them when he was dead? I can't take it....How this movie got so many academy award nominations shows that something is really going wrong in this business!
