The first one is the CGI, it doens't look too bad most of the time, but there is an specific character with and very notorious and bad CGI that just looks like it's made of plastic and that robs part of the seriousness of some scenes. All the robots are CGI too, but they actually have some good shots and some action scenes are pretty good but in general it doesn't work as well as it could.
The story isn't bad, actually it has a few surprises and it's structure allows to unveil it slowly but it feels childish and without tension. There is a nice message about forgiveness but it's taken too far, the extent is taken to makes it seem absurd and stupid. It's events don't have the weight that they should have to tell a story like this correctly.
The characters are ok, there isn't much to say about them. It actually makes an effort to deepen a few of them but they are mostly archetipes so it's not anything amazing. They are characterized enough but not much more.
The soundtrack is ok, a little forgettable, but it does it's work.
In general, it's an amene watching that anyone who isn't expecting much can enjoy. It's short and has some things to say so it has some worth to what it does. Basically, you could watch it as long as you are not bothered by the CGI.
