50 episodes?! SHORT?!
WOW, that's something I've never heard before! But I get what you mean, with as much sub-plots as "Eagles" was able to present, 50 episodes is rather short; but I thought the series was decent in length, it could be a bit longer, focusing on a better ending, but it was fine as is!
^.^ I do miss seeing Hu Ge and Ariel together though; this was my first Hu Ge/Ariel collaboration, so I was completely impressed!
