Pros:

• Overall, good story (albeit a Mashup of a Flashpoint, Crisis, Dark Knight Returns, Man of Steel, Red Son, etc.)
• Great opening sequence!
• Barry's mom & the overall emotional core of the film was strong (but again, Flashpoint)
• Decent balance of tones
• Ezra Miller is less annoying than I anticipated
• Not that the movie have her a ton to do, but would watch Sasha Calle again as Kara

Cons:

• Ezra Miller is still the Flash...
• Awful costuming. Ugh.
• CG overload and it's not very good, probably because every shot has to have 9,000 layers of additional rendering.
• Honestly, I'm tired of movies that primarily "work" because of nostalgia and references to other movies.

I really hope this is peak post-modernism.
