I will save you 22ish minutes of your life. Read the wiki page for the plot of Air. You will get more details and understanding through that then watching this. Also, to even watch this anime, you have to watch it as a 3 part youtube video because no website has this recap episode. Unless you buy the one Dvd set that has the recap. I watched it to see if it did anything different from the anime or retold the anime in a fun way. It did not. You can't even get a full understanding of the story just from this recap because this recapis only for the air arc (The last 3 episodes). I don't even know why this exist. I tried to look it up and I couldn't really find anything about it.

Should you watch this? The better question is why would you watch this?
I genuinely don't know why you would. This is just a weird piece of media
