This movie is passable at maximum. The first half is fantastic sets up the whole movie and gives the audience extra info, its not until Miles becomes a Mary Sue character and just gets his powers when the plot finds it convenient that there really isn't much character development. Certain characters could've had interesting interactions if they were actually developed correctly.
The spidermen from different dimensions were pretty bland despite the trailers as well as having a few moments to shine. The biggest problem the film has is identifying the villain to a higher degree because they threw everything in expecting us to realize thats what the villain was trying to accomplish. Other than that it was underdeveloped characters that made me wonder why the civilians seem to have more personality than the new spiderman from different dimensions.
