Just got back from seeing Wonder Woman- and I gotta say, this film just won back a ton of good will for the DCEU imo. I'm still pretty iffy on how Justice League will turn out, but
goddamn Patty Jenkins and Gal Gadot nailed it with WW.
Best DC film since The Dark Knight in 2008, imo. The only film that rivals it for that title is The Lego Batman Movie.
Honestly, WW just needs to be pretty good to be getting the praise it's getting.
It's like if you had a bunch of siblings who dropped out of highschool and became drug addicts. If you bring home a B on your report card, you're going to get "MY BOY'S A GENIUS!" remarks.
The most I've seen is that it was good, better than the other DCEU stuff (not too hard) and was often compared to Captain America: First Avenger, which was also...good, not great.
That's largely because the film has a lot of similarities to First Avenger in terms of its content (i.e. period piece origin story set during one of the World Wars, an optimistic protagonist wanting to do their part to help better the world from a terrible war, etc).
IMO, Wonder Woman is considerably better. It's not the absolute best superhero film ever, but it's a top notch origin story film and by far the best film in the DCEU to date.
