Superman has never really been my cup of tea- I'm a Batman guy through and through, but I think this looks fun. To me, Superman can easily come off as a bit dry and boring, but I get that it's a fine line to tread. I think he sorta suffers from the same thing that Jack Sparrow does- he's a great scene partner to work off, but if you're gonna focus on him, you gotta do something interesting with him, whether that's make him a bit snarky, depower him, show him through a fantastical lens, etc. Tricky part is, depending on how you go about it, it removes the point of who/what Superman is. He's idealistic enough, like Captain America, where he's that dry, squeaky clean do-gooder in a lot of ways, which, when combined with his literal unstoppable powerset, can easily remove some of the stakes and appeal.
Still, if anyone can add a bit of zest and zing to Superman, I think it's James Gunn. I wouldn't say there's necessarily been a "fun" Superman movie released in my lifetime (to each their own, of course), but it's promising to me that it looks like they're prioritizing some of the fun, and even embracing a bit of the absurd, here.
I know there's discourse and vitriol around everything released nowadays, but it's been interesting seeing some of the feedback for this film. Most of it looks pretty positive, which is great to see, but there's those silly nitpickers too. A big one I saw yesterday was that Superman saving that civilian about to be crushed would've basically made her explode from the force of it. Forgetting, of course, that it's a comic book movie not based in reality. I stopped giving it any mind once I saw that most of them were then excusing Snyder's Superman and how he saved people, because apparently, as one person put it, he "rolled his body to redistribute the intertia".

Who knew there were so many scientists online?!
