At this point, I've only watched Episodes 1-4, so please note that.
I've read the first dozen manga, and own every episode of the original release / OAVs / movies. This was one of my first non-TV released animes, ever. This show is a part of my youth, and is one I love to this day. And I will say that the remake is a love letter to it all. Manga, series, OAV and movies.
Are some moments in the original better? Absolutely. Is the animation different and taking time to get used to? No doubt. Was the original one of the only dubs in the 90s (with Tenchi Muyo!) that was as good as the original Japanese? 100%. But this show is really good. They are doing it for a more modern audience, but the humor is the same. The moments hit all the right points (from Ranma running along the walls to Akane constantly lifting large object to slam on his head... the way he carries her as he jumps... the way the arguments go... all of it). The FEEL is the same. It is different, but that doesn't make it bad.
I give it a 9, versus a 10, because, yes, I do prefer the original ("And I'm better built to boot"... way better than the line they used in this one). But that doesn't mean it's bad. Take it from an old head who has been watching this since 1995... give it a tru, and you will love it.
