I heard that DCEU is giving Black Adam his own movie what are your thoughts on that since this is something that MCU has never tried giving an villain an archenemy at that his/her own movie.

The underlying issue is that the DCEU has the Rock signed up and eager to play a DC character, that the Rock is a legitimate box office draw at a time in which relatively few celebrities actually can drive box office on the strength of their names, but for some reason the DCEU has pencilled him in to play a villain and not a hero and then got cold feet about having him in the Shazam origin story.

Now, Black Adam has more recently been more of an anti-hero than a pure villain, and as I said above the Rock is enough of a legit movie star that maybe he can escape the curse of solo villain movies just not working conceptually or structurally.
