This could have been so much better. Yet, I didn't regret any time watching the series. It was a flash of sparkling potential. Therefore, take a few deep breaths and let your mind at ease before you decide to start chowing down the series, okay ?
The recreation of the 2000 cityscape was a huge letdown. It didn't carry anything that screamt the year 2000 (or at least anything universally recognizable) and also, the modernization of 2022 totaly slipped into frame. So, the visual setting at the beginning was an entire failure.
In terms of the main actor who leads the plot, let's just say he is a level-headed person and his reaction to the sudden change in time and space were mild, that, I can accept. But why did a man like that refuse using hand sanitizer (which was the magical tool to bring him back to his own time) when people obviously say they're in the middle of a pandemic ? Furthermore, he was so sure that he could return to his time when he didn't even know how. He knew how to exploit money from his future lover but didn't have a clue on how to get back, yet, he was determined that he wouldn't have to pay back if he failed the mission (in ep 2). It was ridiculous and illogical.
In addittion, all evidences pointed out that the m.c had switched bodies with another person, yet, I never saw a glimpse of what the other changling was doing in the year 2000, in fact, the director and/or writer decided to actually "delete" the other changling, which makes it...dumb.
And then, the development of the couple just shot right into space on lightspeed in episode 5 (5/10 ep). I was shocked and in denial those were the real events and was not one of the main characters' dream (when they suddenly expressed intimacy out of nowhere). After that, the drama between the m.c and his boyfriend (who had been inevitably made into the company's CEO) just flew into the room like nothing, without making itself clear on why it is dramatic. And...all that was yet to be the end.
However, beside plot holes in almost every single scenes, I truly enjoy evey remaining components of the series. The cast was exceptional attractive, all of their faces captured me in different ways, and I don't have any complaints on that. Even so, the make-up artist actually killed them by not applying colors on the actors' lips, which made them look half-dead. On to the the acting, it was convincing and charming with them delivering lines in their trained tone of voice and completely natural facial expression. I was moved in almost every take. The camera work, the lighting, the camera placement, I love it all.
In short, if set all the plot holes aside, I have wonderfully enjoyed this series. I hope everyone did/will, too.
