This is more a YA rom/com, which is neither very romantic nor at all funny. The script is dull, the plot a bit silly. Of course, it's been done before.
The only part I actually enjoyed was the interaction between the AI buildings... and there wasn't enough of that to really carry the movie.
The acting was mediocre, the script mediocre, the plot... well, the entire film, mediocre. It doesn't really draw in the audience. It's barely fit as a rainy Saturday popcorn movie. Barely B-flick.
It's not a terrible movie, but by no means a good one. Droll is the singular word that comes to mind. Some may find it cute, but the English voice-over spoils it as a family film. Some translation companies should be slapped stupid. Or slapped sane, however one chooses to look at it.
LANGUAGE NOTE: Parents should be warned the English voice-overs contain vulgarity not included in the original Thai version, nor in the English subtitles. I consider that both unnecessary and a betrayal of the original version. Such poor translation can't even be accounted to cultural differences. It was just gratuitous slop translation.
So instead of my standard 5-star "mediocre" rating, it gets 3 stars for raunchy translation.
