A good plot, good music, CGI animation, I don't especially have a problem with CGI, but still CGI lacks the feel of a real anime, and makes it look slightly cartoonish. Therefore 6/10 for animation.
8/10 for the plot, and story, a very comfy and chill start, but taking the required turns for the story to progress. Another interesting plot with the AI and human dynamic which may seem repetitive as VIVY is airing in the times of its release. The end and the use of characters was good, so that also get props.
6.5/10 for the sound, the ost wherever it was used was good, but the problem was there was not a lot of ost, it was mostly dialogue and animation, which created some dry spaces here and there. Well, wherever used the OST fitted, and is done by Kevin penkin, so yeah it was good.
7/10 enjoyment and 7/10 overall, it lacked a certain "UNF" to push it higher, but for four episodes and an 1hr 20 min watch, it was a good enough to provide certain emotions and enjoyment.
I will recommend this anime when two conditions are satisfied, 1) if you have a lot of time , 2) Like the concept of vivy and have no problems with CGI.
Thanks for reading
