At first, I thought that The Sweet blood is an ordinary drama, so I was quite disappointed to found out that it only is shorter web series, because I really liked the concept. After watching the whole thing I still think that this kind of story would be much more eye-catching if it was a typical drama with the usual length and amount of episodes. The web-drama concept doesn't suit it at all and the episodes are too short so the whole storyline seems too rushed and messy at some parts. The plot can be quite confusing with too much and nothing happens at the same time. Also, I was expecting this drama to be action-packed or that it would contain more supernatural things. Because besides some bloodsucking, occasional red eyes, the second male lead's makeup, it looked pretty ordinary to me and the fighting scenes were also bland.

For me the cast was okay, but I must admit that the main lead was pretty weak and didn't have much chemistry with the main female lead. I would look at the vampire or the werewolf with her as the end couple, although it does makes sense that since she wants to live like a human, she would date a human as well. Even though I'm not the biggest fan of love triangles/squares...the main male lead kinda ruins this aspect as he feels more like a side character to me.

The thing that Yeon Seo and the vampires can tell a lot by smelling people's blood was super interesting. I wish the plot was more about finding the murderer and the human blood winery part when it was revealed that the werewolf is actually from the rival team and is double-sided, which would add a lot of interesting parts to the web drama. Especially when Yeon Seo is trained in wine tasting so it would be amazing if she and the others would use their powers and knowledge to find the murderer and then have that huge plot twist about the werewolf revealed.

Overall it wasn't the worst drama ever and I might rewatch it again if I was extremely bored or ran out of dramas to watch, but this definitely has a lot of wasted potential.
