I didn't care for Freddy taking the mantle, it wasn't the clean break that it needed to be if they wanted to pass down the mantle. I thought the inherent concept of the story was cool but for some reason it didn't really resonate with me.
What I did like about it is that it showed more of the magic side of Shazam, and I like that Johns echoed that theme as well by making it more of a visual element with his cloak, arcing lightning and spells. He's always had this origin as a magic hero but he almost never interacted with the vertigo side because he was just too much of a traditional cape hero.
