I was hesitant to do a review on RWBY, firstly because it's been over 5 years since I watched episode 1, and secondly because my opinions on pretty much everything relating to the series, and anime in general, has changed so much over those past 5 and a bit years.
But I have decided I may as well do it now, whilst it's still likely to get a decent score, than after the next volume is released, and I either give it a higher score, or the more likely lower score.
People argue whether RWBY is an anime. Personally, I don't care either way, but I'm going to look at it as if it were one, seeing as that's the general audience of the series.
If I were to say is RWBY is a good anime, I would say no. As an anime it's not really what you'd expect, and the artwork doesn't fit into the anime style at all. However, as a series, you're going to get some good entertainment out of it... until volume 5. It's not the best series you'll ever watch, but if you want an action-adventure series, with a great character lineup, and a good mix of fun and serious, then RWBY is definitely worth your time.
However, this is only really true for the first 4 volumes, of the current 6.
Volumes 1 and 2 focus on the characters' first year at school, and settling in to becoming hunters and huntresses. The environment they're in is fairly safe, apart from a pretty useless criminal enemy, and gives the characters time to become the heroes they are bound to become.
Volume 3 is where the action truly starts to begin, with a decent enemy, and the plot for the rest of the series truly starting.
Volume 4 focuses on backstories and recovery, which adds extra depth to the characters which you are growing attached to.
Volume 5 and 6 are about travelling to the strongest kingdom. Although many things happen along the way, the only way I can describe these two chapters are that they're just about travelling, with a bit of action thrown in. You tell your stories, you fight off attackers, but it's just the happenings that occur between point A and point B, with a bit of bad-guy action along the way.
