Honestly, probably. I didn't see the flash only because it was one of those super hero movies I can watch later or something. My wife also loves super hero movies and didn't feel like going. Not because we felt it would suck, but because we felt it was probably good enough for home watching.
Barbie is something both of us want to watch and are going this evening to see. I'm sure it will have a lot of similar tropes to lots of movies and isn't going to change cinema forever, but it will at least be different enough from super hero movies in general and looks it will be fun.
So I don't hate flash. I just decided to skip it for later as I've done with other DC and marvel movies. They're not different enough from each other anymore. It used to be Captain America as a spy thriller and Thor as an old gods new world type of deal and so on. Now marvel is just average jokes average movie. Which is fine but that's home watching stuff. Maybe an occasional theater watch if we want to get out of the house.
