First three to four episodes are slow.
Lots of historical background. It took many months for me to return to this show because I stopped at like episode 4 or 5. That's a lot of investment (each episode is 1+ hour), but I gave up because of the pace. The romance was attempted, but it wasn't there between the two leads. There was no chemistry between them. Great actors who act well, but no spark.

I only stayed for the bromance. It's bromance show.

And a commercial. This show has the most advertisement I've ever seen. Probably has the amount I've seen in my entire life.

The age gap between the leads though was too uncomfortable. Make the dude a 1,000 year old God at least in the body of someone who looks 25 or 30 instead of 40! The girl is in high school for God's sake. It seems too predatory with a 40 year old dude waiting for her finish high school.
