Sure, here is my unsatisfied review of the 2023 movie The Flash:
* **The plot is confusing and messy.** The movie tries to juggle too many different storylines, including Barry Allen's origin story, his mother's death, the multiverse, and the introduction of two different Batmans. As a result, the plot is often hard to follow and the characters' motivations are unclear.
* **The characters are underdeveloped.** Barry Allen is a bland and unlikable protagonist. He is constantly making the same mistakes and learning the same lessons, which makes it difficult to root for him. The other characters, such as Iris West and Bruce Wayne, are also underdeveloped and one-dimensional.
* **The CGI is subpar.** The special effects in the movie are often jarring and unrealistic. The Flash's super speed looks particularly fake, and the fight scenes are poorly choreographed.
* **The movie is too long and slow-paced.** The movie runs for over two hours, but it feels even longer. The pacing is uneven, with long stretches of dialogue followed by brief action sequences.
Overall, I was very disappointed with The Flash. It is a confusing, poorly-made movie with underdeveloped characters and subpar CGI. I would not recommend this movie to anyone.
Here are some specific examples of the problems I had with the movie:
* In the opening scene, Barry Allen's mother is killed by a mysterious figure. However, the movie never reveals who this figure is or why they killed her. This creates a major plot hole that is never resolved.
* Barry Allen travels to the past to save his mother, but he inadvertently creates a new timeline in which his father is the Flash. This new timeline is full of inconsistencies, such as the fact that Bruce Wayne's parents are still alive.
* The movie introduces two different Batmans: Michael Keaton's Batman from the Tim Burton movies and Ben Affleck's Batman from the DCEU. However, the movie does not do a good job of explaining how these two Batmans exist in the same universe.
* The Flash's super speed is often used in a way that is visually confusing. For example, there is a scene where he runs around a city, but the background does not move. This makes it difficult to understand what is happening.
* The movie has a lot of slow-paced dialogue scenes that do not advance the plot. For example, there is a long scene where Barry Allen talks to his therapist about his mother's death. This scene is boring and unnecessary.
Overall, I found The Flash to be a disappointing and frustrating movie. It is a poorly-made film with underdeveloped characters, subpar CGI, and a confusing plot. I would not recommend this movie to anyone.
