I'm alright with it. In some ways it's refreshing to see a new take on something that's been around for so long. It it works, wonderful. If it doesn't, thankfully we have the classic Superman film starring Christopher Reeve to fall back on for the quintessential Superman.
I believe in Zac Snyder: and Zod; and I'm hoping to God we get a trilogy that features Lobo and Braniac at one point or another. It makes sense for him to be in this series.
This is how it should go if it's a four movie saga: 1)Zod 2)Lobo and Luthor 3)Brainiac and 4)Doomsday. To me that reads like the ideal legacy. The major big-bads are all represented in this list: Zod and Doomsday are the perfect book ends.
I'd fucking love to see Sam Raimie or David Lynch do a 'The Sandman' origin story based on 'Sandman: the sleep of reason'; where instead of introducing the concept of the sandman through some bullshit coming-of-age story, it's established through the old Sandman's night terrors (of his past heroics) as he sojourns in Afghanistan with his terminal wife; and through the hallucinations and panic attacks he suffers as he struggles to save her again.
The new Sandman could be the war-time photographer in the comic. The Sandman to be when he takes up the mask after the old one dies at the end. That way we get a bonafide Sandman the entire movie, and we get an origin story.
