When Ryuga was filled with the darkness, isn't it easier to change it into light? Instead he has to change what's leftover of light into complete darkness. What good does it do?? (other than fulfilling the plot)
Garo series starts to have serious problem since Sho I will say. They put a 12 episodes worth of material into a 25 episode series (Sho), and they put a 6 episodes worth of material into Jinga and this (both are 12 episodes). As a result, all 3 of them are very boring, because they don't have enough material in it (and now, they lack budget too)
Casts are painfully small in Jinga and Hagane. In this series, basically we only have 5 characters that matter (Ryuga, Souma, both priests, and Souma's dad), that's just too underwhelming (in a restaurant they will give you a mid table for 5 ppl
). Zero's bad blood had some good attempts to give some plot to the victims. They have to make the show more interesting and interconnected. Ppl will eventually feel bored seeing painfully small casts wandering in the wild in every other episode
They have to change it soon if they still want to make more TV series. They can't go on like this forever.
