Just got back from the theater; haven't read the thread yet.
I and my family -- who were a bit skeptical, but going along for the ride with me -- all really liked it.
I thought it got Superman's sense of morality and justice right and liked that Gunn and company have clearly seen Man of Steel, The Boys and Invincible and have answers to their POV coded into the movie: You can choose to be a good person, no matter how strong or weak you might be. (Malik, the food cart guy, may be the bravest character in any superhero movie.)
The film also does a good job laying track for future movies -- the Hall of Justice exists, but is still under construction and the future Justice League doesn't even have a formal name yet, although Maxwell Lord is already bankrolling them; Lex is headed to Belle Reve, where he's sure to make contact with people we'd rather he not; the Engineer is still running around loose with a moral compass different than Superman's, making her ripe to form the Authority; we see Stagg Industries and a bunch of other DC Universe references to be potentially picked up later; and Gen. Flagg certainly has some thoughts about all of this, given what happened to his son in The Suicide Squad.
I can certainly see why certain corners of the internet are triggered by this, but if you're triggered by Star Wars and Captain America and Superman, I think the universe is probably telling you something important.
Definitely looking forward to Supergirl and future movies and TV shows in this franchise.
