Agreed; the X-Men teaser moved the needle the most for me but just a shot of a comic-accurate costume isn't going to make or break this film. To your point, Cyclops looks like all those runway AI videos I see where the original actors are in their comic costumes. Very cool but, again, I'm more interested in the story than what they're dressed in.
And I'm dreading yet another X-Men movie with the Fox actors where we have to watch them all die again...Though, better to watch them die, I suppose, rather than just hearing about their off-screen deaths. We've been killing the X-Men since 2014 with DOFP, then Logan, then again in D&W.
Crossing my fingers and toes that the X-Men universe explored in DD is actually the reset 2023 timeline from DOFP. At least draw some connection to the original franchise beyond just the actors. That's one thing that really bothered me about D&W-- here's Hugh Jackman's long-awaited return to Wolverine, but it's not any version of Logan audiences have seen him portray in the past 9 X-Men films he's appeared in over the past two decades. And all the X-Men are dead. Again. But don't worry; Wolverine's wearing a blue & yellow costume and has a CGI mask for 5 minutes towards the end so you can clap and post theater reactions on YouTube.
