METS is a great drama. I'd go as far as saying it's the perfect drama to dive into sageuks. It was my first sageuk and I a real page-turner I finished in only 2 days.

The storyline is interesting, exciting and heartbreaking. It will keep one on the edge of their seats and holding their breath to know what will happen next but there is comedy too so the drama ends up not being too heavy.

I was hesitant when I saw the younger cast would have a lot of screen time but they were so good I wished to follow them from start to finish. They emote so well and were able to play complicated characters.
One can see the trajectory their career paths took and it's well-deserved because they are all so talented.

I was disappointed when the time came for a time jump but I ended up enjoying the older cast as much as the younger one. They managed to stay in line with they younger counterparts mannerism and keep our attention on the drama.

It has great rewatch value. I watched it time and again without getting bored and impatient.
