This special has 2 episodes: a short and bitter-sweet 3 minute video giving more backstory to All Might's grief over his sensei's sacrifice; a 6 minute picture drama that focuses on the after-math of the movie.
The 1st episode is amazing and has a lot of content, despite being only 3 minutes long. I really enjoyed it and if the special had stopped here, I would've given it a much higher grade.
I find hard to enjoy picture dramas (maybe it's just me, though) so I didn't have fun on the 2nd episode, hence why I gave it a 6.
For some reason, MAL is telling me to write more on this review so I'm typing this to see if I can get this review approved. I mean, there's only so much I can type about 2 episodes that last an average of 4 minutes and a half if my math is correct.
