I've seen a lot of reviews that pan the ambiance this show creates for startups. I'm writing here mostly to say, they nailed it! I lived in Silicon Valley (Mountain View and Sunnyvale) from the time that Google had one building, leased from Silicon Graphics, until just a couple of years ago. I had many friends who worked at Google. I attended focus groups and workshops there, and ate in the famous cafeterias. I knew people in other startups and used an incubator for a while with a group I worked with. I had a close associate working for a self-driving car start-up. Start-ups are regularly bought for big money just to grab the talented programmers for a couple of years, and everyone ends up wealthy. It happened to someone I know. The images created in this drama were so accurate that it was like being back there again. So when I say that they got the ambiance right, I know what I'm talking about.
That said, it's not much like that any more - the renown Google food has deteriorated, the people aren't having fun any more, and it's become largely tech rat-race.
AS for the story, it's ok. There were things that didn't go the way I had hoped, there were loose ends. Although I watch a lot of K-drama, I don't pay any attention to the fan wars or other stuff that surrounds them, so I'm blissfully ignorant about all that. I loved seeing Kim Hae Sook, one of my favorite actresses. I looked forward to every episode, and I was sorry it ended. There are plenty pf reviews out there that dissect the plot and everything else in painful detail, so read those if you want to know about that stuff. But if you want to visit the world of tech startups in the early days, this is a great place to do it. They got it right.
