For those that have watched the anime, you'll be disappointed. For those that haven't, it's entertaining enough if you go with low expectations.
I'm somewhere in-between. I watched the anime growing up but I was never a massive fan of it, I generally found this type of anime where fights take episodes to be a basic ok but not much more for me. I liked the world building the most. But alas, I felt the nostalgia and I didn't have anything else to watch at the moment so I decided to check it out.

I don't understand though why they decided to even make this series if they were only going to bother making 5 episodes. It's a case of if you don't have really the budget maybe don't butcher a series with thousands of fans?

I had low expectations since from the trailer it felt cheap and because usually live actions are always pretty bad compared with the original material. It happens here too as expected.
Some of the costuming, and especially the wigs, are cheap and made it look worse than it could have been. CGI was about passable. If CGI has to be immaculate for you then I would say give this a miss.
Acting was ok at some points, at others it was not great, with actors being just standing there expressionless.
Characters are very underdeveloped, I guess can't be asked more for a 5 episode series but it still was disappointing nonetheless. I also think overall it would have been better in my opinion if they had a retro feeling to the whole thing and had more accurate hair to the anime.

Points go because is generally cohesive and the story flows despite the gaps in it and in the characters development, because the action/fighting is entertaining enough and because it's generally passable as a whole.
