Couldn't the Justice League battle the band responsible for 'Magic Carpet Ride' instead?...

Rating: 8/10 (16 November 2017)

The film begins with something Superman obviously filmed before his apparent demise in BvS, then it cut to black, which elicited an "Um...okay?" reaction from my audience. We're next treated to Batfleck vs. insect-man (called a 'Parademon'), which got a "WTF?" reaction. The third reintroduction of a character we'd come to know was Diana's/Wonder Woman's, which was easily the best, as she saved a bunch of people, displayed how effective her bracelets are against machine guns and made you wish you were watching Wonder Woman 2 instead.
Gal Gadot as Diana/Wonder Woman continues to prove she's the best part of these movies (though there'll no doubt still be her detractors refusing to accept this fact). She exudes warmth/compassion/kindness (her final scene in the movie is most "Aww"-worthy), but also strength (and I don't just mean physically). She's everything a team leader *should* be. Diana plays well off Batfleck (even when he's being a jerk). If you're no fan of Batfleck, it's doubtful this movie will change your mind. Thankfully, the others call him out on his jerky behavior (Diana gives him a well-deserved super shove when he brings up Steve Trevor, while Barry lets Bruce know exactly where he stands in regards to him ticking off Diana/what she could do to him and how the team would be on *her* side), thus making Batfleck bearable (Jeremy Irons as Alfred tries his best to create an enjoyable dynamic with Batfleck).
Aquaman, Flash & Cyborg all get short introductory scenes, which leads to scenes feeling like a bit of a shambles, as we cut between them back and forth. Just as something interesting is happening with one, we cut to another. I was interested in the stuff between Jason Momoa's Arthur Curry/Aquaman and Amber Heard's Mera (who seems to kick a reasonable amount of underwater butt), but it was sadly cut short and she didn't appear again. At least Aquadude brings a different sort of personality to the team.
Ezra Miller's Barry Allen is much more manic than we've come to know him as in his TV iteration (though I think Grant Gustin's scenes with his onscreen father have this movie beat). He provides the majority of the 'comic relief'. He may start to bug after a while depending on your tolerance level for such characters. Some of his jokes work and some don't (much like Batfleck's attempts at humour). I think the 'humourous' moments work best with the characters you LEAST expect them from, such as Diana, Alfred and (to some extent) Arthur (there's a particularly funny moment involving him and Diana's Lasso of Truth).
Ray Fisher does quite well as Victor Stone/Cyborg. He's not given a lot, but makes the most of what he's got (the CGI didn't bother me). Everyone acknowledges Diana's obvious awesomeness (they'd be fools NOT to). Her ability to hold her own/lead is never called into question by the other characters (nor should it be), which is refreshing (unlike certain other superhero team-up movies). It's Diana herself who experiences some self-doubt, which she overcomes; she saves everyone's butt on more than one occasion.
The team all saves each other, actually. It's never a case of one person doing everything/'taking all the glory' (again, unlike with a certain other so-called superhero 'team'). They work well, and it's good to see Aquaman, Flash and Cyborg all respect Diana. Speaking of, complaints regarding 'lingering shots' of Gal Gadot being 'exploitative' have been rather overblown. There's no more 'leering camera' on her than there is on at least two of the male heroes who have their shirts off at one point or another (and what about all the male shirtlessness we're subjected to in other superhero films? How is it that's 'okay', but a 'butt shot' of a female character here or there upsets everyone?).
This film's unnecessarily CGI'd villain, Steppenwolf, is just another forgettable comic book movie villain (so...basically the usual)). The most memorable part involving him is a game of 'Keep Away' the Amazons play with this film's McGuffin ('Mother Boxes') on horseback. I wish we could've spent more time with Diana's people, along with Aquaman's, as I would've gladly given up all the Lois/Lois & Clark scenes (as well as most of the scenes focusing on a random family in need of rescuing) in exchange for more Amazons/Atlanteans.
Obviously Superman eventually returns. This version of Lois & Clark continue to be the most chemistry-free comic book romantic pairing, scenes between them kill any momentum/bring proceedings to a screeching halt, and watching them trying to be 'cute'/'funny' is painful (they waste time talking in a cornfield when he's most needed to help the team and Diana's forced to do the heavy lifting in his absence). Henry Cavill's Clark/Superman works much better interacting with the other heroes. It really should've been Diane Lane's Martha (instead of Lois) playing the 'important' part in calming down the freshly resurrected, not to mention dangerous to his teammates (just look at Flash's "Oh, crap!" face in reaction to Superman super-glaring at him), Zombie Clark...especially considering how important Martha was in BvS. Also, I would've preferred anybody but Lois providing the movie's end voice-over.
If you dislike battles filled with CGI, then...sucks for you, as there's plenty on display and not all of it works, but there are some decent action sequences, and it's interesting seeing everyone's abilities/fighting styles on display. The score uses some old themes (I missed John Williams' 'Superman Theme', which MoS sadly lacked, but I caught Danny Elfman's 'Batman Theme') as well as the always awesome/welcome 'Wonder Woman Theme'. The ending feels a bit abrupt in a "That's it?" sorta way, and there are two credits scenes (the mid-credits one reminded me of similar scenes in Smallville and Supergirl, involving two superheroes racing. If you don't like Jesse Eisenberg's Lex Luthor, there's no reason to wait until the end). The Justice League has united/'come together'...so, now what? Answer: Bring on Wonder Woman 2! What? We have to wait until 2020?!
