Yeah... Crisis likely gave us the only Arrowverse DCEU crossover. What an awesome Flash moment. Loved it!
I liked the promo for the first movie with Melissa and WW boots.
I mean...The Flash movie looks like it's going to play with the multiverse...and it'd be a nice return of favor to have Grant make a guest appearance.
But yes...in my dream crossovers, which won't happen, our Arrowverse heroes would get an epic giant movie crossover with the film heroes.
In my mind, they should have had Crisis be an actual film or HBO Max mini series, with movie level value, using these concepts. I know studios wouldn't jump at it...But man, they could take all my money. Getting our Supergirl to interact with movie kryptonians, and other classic DC Film heroes? I would absolutely lose my mind.
