I went in expecting nothing...

Rating: 4/10 (22 November 2017)

...and that's exactly what I found.
The plot is basically copy-and-paste from the first Avengers movie. The digital effects look like they are something out of The Mummy Returns. There is essentially no character development, which would be fine if these were all firmly established characters, but they aren't. Aquaman, Flash and Cyborg are all making their first movie appearances. The Superman that we see here bears very little resemblance to the character of the same name from Man of Steel and Batman vs. Superman.
DC/Warner Brothers seem to have taken previous criticism of the previous movie being too dark and joyless to heart and has horribly over-corrected. There are lots of jokes to be found, most of them not good, in my opinion, though sense of humor is highly subjective.
Gal Gadot is good but there's nothing on the page for her to work with. Henry Cavil is like he always is, which to me comes off as stiff. Affleck seems like he's increasingly desperate to remove himself from this series and can't be bothered to even really try. I've never been a fan of Ezra Miller in general, and his portrayal of Peter Parker... I mean, Barry Allen, does nothing to change that. I don't understand how it's possible for Jason Momoa to be this uninteresting, as big and magnetic as he is in other things, he comes off as completely uninteresting here.
I can't help but feel like Warner Brothers were worried about releasing another critical disaster like Batman v. Superman and settled for making a boring movie instead of a terrible one. Personally, I don't know if that was the better choice or not but you can easily give this one a pass.
And with this, I am officially done caring about the DCEU as a collective entity. The Wonder Woman sequel is almost certainly worth checking out. The Flash and Cyborg solo films? I'd say they may not even get made at this point, considering the once-again disappointing box office numbers. Hypothetical Future Justice League movies? Not without and serious, fundamental course correction.
