This flash feels like a jigsaw puzzle with mismatched pieces. While the script itself shows some promise, the movie stumbles, primarily due to its abysmal CGI. The effects are so poor they break immersion, leaving you disengaged from the narrative. The film's attempts at humor are painfully forced, so much so that I found myself questioning my commitment to the DC universe halfway through. Casting is another sore point. Ezra Miller's portrayal as the lead character is not just lackluster but actively detrimental, reminding me of an episode of "The Big Bang Theory" more than an epic superhero tale. Thankfully, there's Michael Keaton, whose return as Batman is a nostalgic delight, bringing a sliver of gravitas to a film that desperately needs it. All in all, this movie is a largely disappointing affair, with only Keaton's performance offering a glimmer of redemption.
