I will have to go with a mixed bag on this one. I am a huge fan of the original Japanese Anime since it came out. It is easily one of the best anime series ever done. It has a great feel, highly interesting characters, amazing music, and a style all its own. it sort of feels like if Robert Rodriquez directed a 007 film. It has a solid, dark story arc that unfolds over the 26 episodes. It doesn't reveal the whole thing at once though, the actual story is maybe 5 episodes of that which are interspersed throughout. The rest is back story and filler for the other characters and how they blend into that story as they become friends of, and aid, the main character on this journey. This series has a huge following.
When Netflix announced a live action version, I think fans all immediately got excited and in the next moment, all knew it would be extremely difficult to deliver something that would meet fan's expectations. I'll be honest, what they delivered was not bad. It has the look and feel, and it bears a lot of resemblance to the original series. They nailed the main characters so far. I feel they may have obsessed so much over making the characters true to the previous series though, that they forgot or rushed the new stories. I understand they do not want to deliver a shot-for-shot reproduction, because nobody wants to see that really. However, they went to the opposite extreme, changing almost every single storyline. Some of the changes are to minor details that effectively do not add any benefit nor were they done to achieve a "current times update". Some of the things changed are little bits of what made the original so good and so far, of my group of family and friends who are fans, nobody likes those changes. I am not sure what the reasoning behind some of the changes are, but they seemed unnecessary, as if to change it simply to make it different from the original. It would be like remaking Home Alone and Kevin gets shot but lives.
I don't outright hate it, but I wouldn't call myself a fan of it either. I enjoyed what was done, but I'd expect long time fans not to like it either. It is an entertaining watch, with some nostalgia for fans for sure. For those who have not seen the original at all, I would expect many will enjoy it. If you're a newcomer, I'd say give it a watch and if you like the first episode, you'll enjoy the whole thing.
