I'd be interested to see a Matthew Vaughn directed Superman film starring Cavill. Cavill hasn't wowed me in the role yet, but I think the right direction and script he'd be fine. I think he at least deserves a chance in a non-Snyder film.
I don't see a whole universe reboot coming anytime soon. They will probably just pick and choose which elements to continue and which to ignore. The solo films will take priority over the crossovers. Maybe they'll do Flashpoint to reset a few things, like if Affleck leaves. They're not gonna mess with Gal as Wonder Woman though, obviously.
Man, is it just me though or does the whole release of Justice League feel so anticlimactic? It's supposed to be the biggest DC movie of all time, and it just feels like an afterthought, something to mark the time until Star Wars comes. All the green screen makes the movie feel smaller in scope. Affleck looks like he's checked out. Just doesn't feel like the event it's supposed to. Which is sad because that was the whole reason for shoehorning so much into BvS. I'm open to the possibility of JL turning out to be an entertaining movie, but from the clips it just feels painful. It really does feel like they made a TV movie sequel to BvS. It's the green screen. Compare the rooftop meeting with Gordon to any rooftop scene in TDKT. It's the lighting. It feels so artificial in the JL clip. It feels like we're back in the 90s all over again, only instead of the studio backlot feel it has the green screen feel. Where they are trying to give it scope but something just feels off.
Good thing WB has had a good year with Wonder Woman, Dunkirk and It...they can probably afford for this to potentially underperform. I feel like even they aren't expecting much from it, just feels like it's being kind of dumped out here and they're anxious to focus on future DC movies.
