Well, pretty much what I was expecting...
After spending the last day or so checking out various spoiler-free reviews, it seems that almost EVERY 'Professional' critic absolutely despises almost everything about this first part of the story. It's currently holding something like 24-26% on RT, with no audience scores yet, of course, since the premiere is still 5 days out.
Interestingly, the non-pro folks that have seen it seemed to range from "really enjoyed", "looking forward to part 2", to full on "Loved everything about it", which is about what I figured.
The really funny thing to me is that whether the movie is liked, loved, disliked, or hated, almost EVERYONE has the same takeaways...
-The movie is 100% Zack Snyder
-It's a combination of Star Wars, Seven Samurai, both the magazine & movie Heavy Metal, with a bit of comic book sensibility
-It lays it's world-building foundations with a lot of spoken exposition, with the promise of seeing it still to come
& Lastly
-If you don't like Zack Snyder movies, YOU WILL NOT LIKE THIS ONE
Now the funny thing to me is, almost everyone agrees on this things, but depending on the reviewer, they're framed as either a positive or a negative. For example, I saw two reviews from the same site, with one reviewer calling it a SW-like adventure without having to shoehorn the story into 40-odd years of canon, & the other calling it an expensive SW knockoff. LOL
Either way, I'm looking forward to both the part one & two, & the extended cuts that will soon follow.
