I finally saw this tonight with my spouse and MiL and we all enjoyed it quite a lot. Despite all the discourse, I didn't really quite know what I was going to get, but after the first couple of minutes I just thought, "Okay, it's a broadly-played, big, stagey musical. Got it." and was entertained throughout after that. I thought both Gadot and Zegler worked in their roles and there were plenty of laughs.
From a modern perspective, the original doesn't have enough story to hang a hat on -- it's really about the iconic imagery -- so the expansions here felt warranted with plenty of nods to the source material intact. The design of the dwarfs was indeed a bit off-putting, but if they're going to be the source of a lot of pretty extreme visual gags (just like in the original) you almost have to do it that way -- I don't think Three Stooges-style buffoonery would've worked as well.
This movie deserved better, and I've given up trying to figure out what the people looking for solid family entertainment find acceptable anymore. Is it the greatest movie in the world? Of course not, but neither is the vast majority of family movies (including a majority of Disney's back catalog).
