Let’s divide this film into two parts: The first 98 minutes and the last 35 minutes.
The first 98 minutes could be fun for someone 12 to 17 years of age. For me I rate this 98 minutes as an F – Marty came in at D. It was slow and boring and immature. I took a long potty break and checked the time often. This was 98 minutes I will never get back.
The final 35 minutes was very good. When The Bad Guy (no plot spoilers here) recognized the good guy the pace of the film shifted into high gear and ended strong. Marty gave this portion an A and I came in at B+.
Still the strong close was not nearly enough for me to encourage you to go the theater to see this film. Wait for home viewing where you can get something to drink, read the paper or a magazine, go to the bathroom and be ready for the final 35 minutes which was excellent – due in large measure to Michael Keaton.
After this disappointment they will not get me to buy a ticket for the sequel.

But did you wait till after the credits when they showed Michael Keaton in prison defending Peter? Captain American also came on after the credits. It’s a set up for the future as he matures. I loved that they had Michael Keaton, you remember when marvels started on TV, Michael was the first Batman. I agree the first 5-10 minutes were a littel disorienting just to make the connection, but after that you are watching a kid grow up. I loved Wonder Woman!
