As a film it isn't great, as a bingeable series it's pretty decent.
Some stories make great self contained movies that can last two hours, and some stories need that extra time.
If they had broken it up into episodes, which they couldn't do because of contracts and pay, Snyder may have made it more episodic than even it was with the title cards.
It's too bad Warner has declared the Snyderverse done.
If I were Warner I'd be running multiple Batman/DC series. I've always wanted there to be 10 directors each making Batman/DC movies at the same time. Each auteur has added new flavor to the series. The courses have been over-staggered. I could use a plate with more than one item on it. I still want that Ben Affleck written movie with Deathstroke. DC shifted to Matt Reeves because they got skiddish with Affleck after Live By Night tanked even though he directed the Gone Baby Gone, the Town, and Argo. As great as Matt Reeve's The Batman looks like it's going to be it seems like that was an impulsive decision. Porque no los dos? Why not both? If I were at&T looking for content there would be an HBO original Ben Affleck movie on the way.
