Venom and Doom have a legitimate shot and have piqued my interest, the rest are nothing.
Back in the day, Silver Sable managed to sell half a million copies and lasted for 30 issues. Don't discount that one.
I feel like right now Disney/Marvel know what they're doing. My main complaint is that they aren't trying to get the Hulk distribution rights back nor work out a deal with Universal who could do spin-offs for Red Hulk, She-Hulk and Totally Awesome Hulk. The latter deal works since Universal's monsters franchise has had two flops and zero hits. Same goes for not trying to get shared rights to a certain number of Fox characters who really belong in the MCU (Kang, Annihilus, Blastaar, Juggernaut, Henry Peter Gyrich, Abigail Brand, GW Bridge, all Shi'Ar, all Badoon and all Brood).
Fox are moving in the right direction but Future Foundation sounds bad so far. I'll remain cautiously optimistic since I feel like Silver Surfer would be a better choice compared to Future Foundation since there's more material surrounding the Surfer than there is for the Richards children.
Sony are quickly running out of ideas. Venom and Silver Sable are interesting in theory but untested as lead characters in live-action. Mysterio and Kraven could be good but will likely flop since I don't trust Sony to know what they're doing. If the Kraven film is an adaptation of Kraven's Last Hunt and involves Tom Holland in a supporting role, then I'd be pleased. I still have very little faith in Mysterio since it's hard to imagine that being good.
DC/Warner are the real problem. They're greenlighting too many films but only have release dates up through 2019 while only doing 1-2 films a year. Disney and Fox at the very least are dividing their properties up between TV and film. Warner prefer to double down on the same properties in two different mediums and have two different versions of Superman and The Flash running around at the same time. And now there's talk of a third universe with a Joker spin-off and an additional Joker film set in the DCEU. The Joker only works as an antagonist because he has no redeeming values. The second you humanize him is the second he is no longer interesting. DC also need to worry about too many franchises and how that creates long waits between sequels. DC simply are biting off more than they can chew and focusing on obscure properties rather than getting their A-listers established. For instance, Shazam and Suicide Squad coming out before a Batman solo film is a horrible idea. I'm actually shocked that Suicide Squad made money despite being critically reviled and an obscure property with poor word of mouth.
Here's a best case scenario.
Disney work out a deal with Universal for a Hulk franchise. They also work out a separate deal to get access to specific Fox characters.
Fox manage to use the Future Foundation film as a springboard for a new Fantastic Four film without having to retell the origin (which is good since Fox managed to botch both the 616 and Ultimate origins). We get a Doom who isn't tied to the FF's origin story. We also get a Silver Surfer spin-off. And kids wind up loving the new take on the Fantastic Four through Future Foundation while adults like Doom so Fox hit s broad audience when it's time for a new Fantastic Four film.
Sony somehow manage to make a good Mysterio film and base Kraven on Kraven's Last Hunt. Neither of those films get a sequel and instead we get Spider-Woman becoming a third spin-off franchise.
Warner wind up canceling both Joker films, Dark Universe, Black Adam and Cyborg, refocus the DCEU on core properties while canceling Batgirl and replacing it with Joss Whedon's Justice League 2 (Batman, Superman, Wonder Woman, Nightwing, Green Lantern, Flash and Aquaman). Shazam won't get a sequel. Crisis on Infinite Earths film happens and winds up merging universes with the Arrowverse. Flash TV series is canceled and replaced with Batgirl. Gotham also canceled and replaced with one of the Dark Universe Heroes or Sandman.
