Babe, I hate to break it to you, but people factor in writing, chemistry, and more in how they score any movie or TV series. If Revenged Love has a better written story and better chemistry between the leads, than it's IMDb score would have reflected that.
Actually, because both series scored so similarly, that suggests most viewers don't think one is better or worse than that other. Which I find quite reasonable, since I love both series (hard as it may be for you to understand).
