Hmm the news about the solo movie makes me think those rumours about Batfleck dropping out could be true.
Green Lantern was awful, but that was just one film, so the character certainly isn't cursed... yet! Unlike the Hulk anyway (got to get my dig at Marvel in here somewhere).
I understand why people would find Aquaman to sound terrible, because on paper he definitely looks that way... but I reckon most will be pleasantly surprised by him, especially with Momoa portraying the character. Put it this way... the Earth is covered by about 70% water, and Aquaman rules it all!
As for Flash... I think he looks awesome and hilarious, so I can't wait to see him in action.
