I think Aquaman has great potential. I'm not sold on Momoa yet, but he has a great opportunity to prove me wrong. Maybe I'm old-school, but I want a serious Aquaman, not a surfer dude.
Shazam photos looks cartoonish so far. Again, I'm not sold on Levi playing the part but it may have more to do with him reminding me so much of Jimmy Fallon that it's hard to take seriously. He was very good in Chuck, so we'll see. The costume padding also seems silly. I think he bulked up some for the role but you would need someone huge to fill that suit properly. But if they can pull together a funny, charming script, it could be a monster hit.
