HAL
I'll be totally honest, I didn't really have a lot of interest in this film and the only reason I own a copy is via AL's Mystery Box. However, with me picking what anime to watch with a randomiser, I ended up watching this tonight, and it was pretty good, but not without it's faults.
First things first, this is a brilliant looking film. Only anime I've seen from Wit before, to my knowledge anyway, is Attack on Titan, and whilst the art style here is very different from that, obviously, it still looks every bit as nice, if not better, most likely benefiting from a higher budget. The rather unique structure the film has is another point in its favour. At first, I was rather annoyed and somewhat dumbfounded that the film's first scene being Hal's death. Knowing the premise of the film from the back of the box, I thought we'd at least get to spend time with him first to establish the relationship that was in place before Hal's death. However, it turned out to be quite a good move, as I really liked the way we found out about Hal slowly from the other characters and from camera footage.
The romance between the two leads was quite sweet, but I found it to be lacking any emotional resonance, at least not with me anyway, and I think a lot of that may be down to the female lead Kurumi, whose entire character is pretty much defined with her relationship to Hal, as we don't really know much else about her, other than she likes sewing. I also thought turn the story takes at the end could have been handled better, and it was a little vague what was happening, specifically is the Hal we've been following is human, and if so how/why did he choose to get his memory wiped and replaced with that of a robot? If the Kerumi was a robot intended to make the human Hal feel better, why not just have a robot Kurumi visit Hal's house like Hal did to who he thought was the human Kurumi? It just needed a solid explanation rather than vague visuals.
Despite some issues, at only an hour long, I'd still recommend people check this one out, especially if it's just been sitting on a copy from the Mystery Box.
