So I finally watched 5 eps of this, expecting generic shounen bs, cringed at the terrible opening, and then HOLY SHIT AWESOME! The first three eps were fucking amazing: great animation, stylish as hell, non stop action..
Then: Eps 4 and 5, not so good. Animation suddenly more static and less awsome, plot descending into boring shounen cliches: lessons about "true bonds", heroes finding village ruled by evil priest and liberating the people.. bla bla.. How many times has this shit been used anyway?
So what happens next? Does the awesome from the first three episodes return or should I quit now?
Yes and no. It has a mix of both the good and bad you have stated.
Just keep watching.
Episode 4 was awesome, shitfucking idiot.
