This is one of those dramas where I really don't know where to begin when reviewing it - positives and negatives all the way, to be honest.

First of all, the storyline that it contains just didn't really have enough material to work properly for the length of the season - it's 32 episodes this season and a further 20 in season 2 and I wonder whether it would have partly worked better if the split had come at the apparent cliffhanger which happens somewhere in the mid-20s. That sees our ML and FL make a significant decision which propels the story into a whole amnesia/time travel subplot that I just wasn't expecting and would probably have made a good point to end that season. I haven't watched the 2nd season, so I don't know if it's going to get resolved early on in that season or if they're determined to milk it for everything it's got.

As for the main characters, the FL has a lot more interesting backstory and character opportunities, while poor Darren gets stuck with a lot less to work with as the ML. The secondary couple are both left to pine for people they can't have, with the secondary ML's attitude annoying the crap out of me very early on. Other than them, the supporting cast are pretty good and I particularly liked the guards.

The production quality is pretty good and the CGI isn't terrible, so it's watchable. The main drawback is that the writers seem to love unnecessary drama caused by lack of communication and so the main relationship fractures and rebuilds a couple of times. This show would have been so much shorter and more balanced if characters would actually trust and talk to each other (see Imperial Coroner for a good example of how this works!) and even that cliffhanger might have hit at least half a dozen episodes sooner.
