This series is good, but not perfect. One thing that bugs me is the characters. While the personalities vary and their interactions work, they are all cliche anime stereotypes. You have the head strong egotistical character, the overpowered loner, the annoying comic relief, the group leader and the attractive female that obviously has a crush on him. I mean they aren't that interesting or unique, they are the same characters we have seen hundreds of times over.
Also, too much dialogue and recycling of animation. The voice acting was good atleast, but rather than having that text box come up, you should focus on animating the whole thing properly as apposed to mostly talking with a few animated cutscenes thrown in. Those were the parts I liked the most.
Yes I know you can look at the massive pack of 5 star reviews with people saying stuff like "YOU'RE AWESUMMM, UR STUFF AMAZES ME!!" and that's cool, but remember there is always room for improvement and I see plenty here. Try and mix the characters up a bit and focus more on animating it instead of those recycled poses during the droning talk scenes.
Overall though, I look forward to the next one :>.
