There are expected controversies around how faithful it is (or should be) to the source material - some points are literal retelling of the story, some are drastically different. I think it's mostly good that they're changing the story at times, it's a new material and a new medium after all. And I think they actually are the story difference are actually fixing the issue of the source material where the story was not sufficiently told in the end.

What's really great about the live action series is a visual style - it's realistic (the CGIs are mostly about space and some background imagery) yet very bright and vivid and ever-so-slightly goofy. The pace and character development is also great, it's all coming together nicely.

But it's a real hit-and-miss in the actors department - some of them are really in the right place and the resulting characters are truly great (like Spike and Jet), some of them come unbalanced (like Faye), and some are a complete disaster (like Vicious and Julia), which is really irritating.

It's still very worth the time, for it's a quirky and goofy blend of visual greatness and great characters.
