Good, but not quite satisfying
Don't get me wrong, you have no idea how glad I am to see this. Action series on NG are damn near extinct, and I thank you for picking this up again. Unfortunately, this Flash has alot of what turns people off from this genre of Flash in the first place. I remember the first episode from 3 years ago, and I went back and watched it again, and actually liked the approach more.
As far as graphics, I'm not partial to the new psuedo-3D style, the animations are very slow and awkward, especially the action parts; I really liked the 2D characters with more organic 3D backgrounds like the last one, I don't understand the change. The sound quality was decent, but the acting could use more realism; I felt constantly reminded that I was watching a cartoon by the characters' Saturday morning anime dialogue. Lastly, and most significant is the storytelling, this cartoon feels like you got impatient and dropped it halfway through. It is NEVER a good idea to leave the audience hanging in the middle of an action scene. That doesn't make me eager to see the next episode, it just kind of pisses me off.
It just isn't satisfying. I get the fact that it's a series, but with the best series, EVERY episode is watchable and re-watchable. This episode doesn't accomplish anything storywise or content-wise. The only thing I know more now than 3 years ago is that there's shadowers, and some alternate universe... Mmkay. If it's an action series with a story, something significant in the story should happen, not just... something... Please don't take the "I promise future episodes will be badass!" method, I can promise you that nobody sees your vision the way you do unless you put every ounce of your being into every chapter of this tale. Make every episode count, if it's not helping the story, give it a badass fight, if it doesn't have a badass fight, mindfuck us with intriguing revelations. Okay, I'm done. I'll be watching the rest of the series still, keep working at finding that balance.
