Yes, it was amazing at first, but it went downhill once Episode 3 dropped. I loved the four trailers and RWBY Episode 1. They all presented a gritty feeling, amazing action and a fascinating fantasy world that could potentially be full of lore. The first episode started amazingly and went straight to the action. We get to see that the world of RWBY is full of different factions. The comedy in this episode was also top-notch.
I wanted a gritty world-exploration anime with many factions around the world and the team slowly meeting each other over the course of time, so that we can gradually understand each of the characters one by one with the creatures of Grimm being a threat that's always there.
Instead, we are thrown into a school and all the characters meet at once. Leaving me to assume that they're saving everything for later. At that point, I thought the school would send the students in missions against the creatures, but instead we get school drama that isn't very effective. The comedy in the school part of the series is far from what we were shown in the first episode, in my opinion.
The voice acting could use more work, but it's good enough not to be annoying. I expected Red vs. Blue quality voice acting, which the first episode was able to do, but the rest of the series was unable to even reach that level. And then the final episode is underwhelming. Action is truly the one redeeming quality RWBY has.
But overall, dispite the disappointment, I liked it. I'm excited for volume 2 and I'm hoping that everything done in Volume 1 was just to save the good stuff for Volume 2.
