Let’s start with the short version: Yes, it is better than Batman v Superman: Dawn of Justice. Yes, it is a big-screen movie. Yes, it has some good (if flawed) entertainment value.
Now for the longer version: Little was going to completely rescue this movie. It was coming out of a long history and vision which had set the tone and approach. It was very much in the can before Joss Whedon (Avengers) was brought on to finish it after Zack Snyder’s family tragedy. Whedon brought some bright spots in dialogue and character, but the main structure of the story was set and there wasn’t going to be a massive rework.
One of the big draws for this installment was the return of Wonder Woman. Mind you, she is far from the focus of the story. In fact, no one is really the focus of this film, which is part of its flaw. It also suffers from a slightly different angle on the issue that Thor: Ragnarok has. Thor has a big “surprise” a third of the way in that we all knew because of the adverts. It didn’t ruin the movie, but it diminished the impact. Justice League is structured solely to get Superman back so the League can exist. Despite that, more than half the movie passes before we get to that goal and intent and, instead, we wallow for ages with guilt and battling a villain we don’t really care about (and whose CG was appallingly bad and whose character resolution was head-scratching, though that may be because I didn’t know the Darkseid background).
Despite those issues, there are lots of good moments that help buoy the weight of the plot. Whedon’s dialogue is primary there…mostly in the guise of Adam Driver’s (Silence) Flash and interchanges between the characters. If you want to see all the bits and pieces that Whedon changed, here is a near exhaustive, and spoiler-rich list. Definitely insightful and with only a few surprises in ownership.
Justice League serves as a bridge away from the Zack Snyder era and into whatever is next for DC. For the moment that looks like it will be Joss Whedon influenced, which could be the best thing to happen to them since Christopher Nolan. I would actually argue that is better that Nolan because Whedon is a much more entertaining storyteller overall, but that isn’t the discussion for today.
Snyder, for all his faults as a writer and director, has a singularity of vision and was in the forefront of defining how Hollywood brought to life a true sense of comic books. It was an unrelentingly, navel-gazing, and ultimately ill-conceived view, but it was undeniably well-intentioned on his part. Most movie-goers aren’t sorry to see him leave the fold at this point, but we shouldn’t begrudge him the props he is owed for getting us here nor deny that he may return again triumphant when he is ready to take up his seats again behind the camera.
As to Justice League… yeah, go see it. It isn’t the train wreck you fear, even if it isn’t the glory you’d wish for. It is an important stepping stone to whatever is to come and it really does deserve a big screen the first time you see it.
