-the plot and characters : the story is about a tow free journalist Shirasu and her senpai that where involved religious conflict in udeiana , with UNF trying to stop this conflict in this mess shirasu takes a picture of a flag that later becomes the symbol that created a road to peace in that country , that about what i can give as summery for the plot without spoilers , the plot is well paced its not to fast or too slow every ep gives a great amount of content from character development , interaction and plot development , the story is character driving as every element is explained by ether character interaction or there action considering the style of the story telling as this anime is in the format of a documentary made by the main characters there is a lot of explanations and dialog and i love how the mechas are portrayed here realistic as it get with lots of attention to there details , also this anime is kinda of heavy as every ep is full of information and details so watch it in little doses ,
- the art and animation : first the art style is kinda western different from your regular anime and gives a unique feeling , the characters design are realistic to try to add more realism to this anime in its world , the animation my god i never saw something like this the way this anime was animated the camera angels extra , seceded in making this show look like a documentary as it was taking from the cameras of the journalist it makes you feel like this was not animated but it was took by the cameras of the main duo and it looks beautiful ,
-music : the op and ed where nothing special not catchy or good songs but they still give you the feel of the anime , the ost there is not much to say about it as it was non existed there where tracks here and there but this add to the feel of a documentary ,
-overall : "FLAG" gave me everything i want to see in a real mecha anime i loved this anime it was a great ride gave me feels , i may have being a little based in this review as i love this genre , so you may not enjoy it as much as i did but i advise to watch it if you have the time
