First of all ignore "Genres: Comedy, Ecchi, Slice of Life" part. This and the fact that those are shorts really give wrong impression about what this picture drama is.
So, what it is then? Just as first season's specials, those are short stories focused around R2 story, with some telling about things from past and last episode happening after R2 epilogue. The reason why I'm saying to ignore genres is how meaningful this special is. While there is some fanservice, all episode add to the main story and are on the serious side. Some also hit in the feels.
Just as the title says, it's a picture
drama. In other words still frames with voice (and subs) telling story. It's worth mentioning that art is far better than in previous picture drama - here all episodes use same drawing style and move "panels" through screen for better effects. It looks less like random collection of leftover frames put together into something and more like actual work of art.
Personally I really liked the way it looked and didn't have any problems with it not being full animation.
Characters and music are from main series, so there is no reason to comment on that.
I really recommend watching it to anyone who enjoyed both seasons of Code Geass. Even if you generally don't like picture dramas, I encourage you to give it a try - it's worth it.
They stepped up their game with these picture dramas. I wouldn't say that the overall score I'd give them changes much, but they're more enjoyable.
Each mini episode is suppose to be a comedic scene that was cut somewhere between episodes. As you watch these specials, it'll become more clear. It's very obvious that some of these events take place between or after certain main turning points in the story. The comedy is a little better this time around, but it's still nothing spectacular. The story part earns a 5/10.
The creators still used the same type of still picture art style
that used in the season 1 picture drama specials. It's kind of visually appealing, but I wish these types of specials didn't pretty much always rely on still shots or chibi art. I seem to only ever see these 2 art styles used for picture drama specials and others like it, such as the re:zero break time stuff. It's kind of a dull way to portray art in an animated work. 5/10.
For the most part the sound is unimpressive, but it seemed like more of the scores were used from the tv series than there were in the season 1 picture drama specials. Those music scores keep the sound from feeling completely stale. 5/10.
Nothing all that new in the character department, but their personalities are kept in tact. 5/10.
Now, I did enjoy these picture drama specials more, so my enjoyment earns a 6/10. They're a bit funnier and overall, a slightly more enjoyable ride.
