This is an ok mini-show. The numbers say that the episodes are 15 min and there are supposed to be 30. I don’t know where the fault lies but the compressed movie-version is only 1 hour and 11 minutes long.
The storyline is interesting and the reason I ended up watching. Sadly there is not enough happening, so the show ends up feeling a bit bland. At least it has a happy ending.
Acting wise there is room for improvement. ML is rather stiff even if his facial expressions are fine. The chemistry between the couple is almost non-existent and the transitions between some of the scenes are a bit odd - like the editing (into a movie-version) is too poorly done (since it is a mini-show that is most likely what happened).
Anyway, if you watch it for the kind of interesting alien story, this is an ok watch.
