I've never been to interested in series based around MMOs and esports, so I wasn't really expecting to like this as much as I did.

Storywise, The King's Avatar is super interesting. I really like that it only centered around the game and there weren't any romantic subplots. The focus is more on character evolution and they're all super likable. It probably has to do with the acting, which is pretty good as well. I'm particularly surprised with Yang Yang. I really didn't like him in Love O2O, but he does an excellent job here. Ye Xiu is a very fun character to watch.

Another surprising thing about The King's Avatar is the animation. The game segments actually look like a game. They're also very cinematic and visually pleasing. Music is also great. There are some nice themes here and there.

Overall, I'd say The King's Avatar is worth a watch. It's a little long (although average in length by chinese drama standards), but it's also fun to watch.
