Re: spiderman in civil war (mild spoiler if you havent seen new trailer).
I think it's terrific.
For those of us who have known the Ditko and Romita Spider-Man since the 70's and 80's in the comics this is really tugs at the heartstrings - we get it. This is the Spider-Man as he was meant to be at the start - a high schooler in a low tech suit. In the comics the artistic license allowed for some change in the shape of the eyes to give some way to emote - at least artistically. They found a way to translate this into a technological construct to allow for the same effect and I think it's absolutely brilliant. I'm sure the eyes, in this case, were designed with the help of Tony Stark. In the end it is just a wonderful artifice to allow us to see the original comic on the big screen.
For the other folks who are more familiar with the movie versions with the raised webbing and the textured material (or the later comics with the huge eyes), it might seem a bit unsettling. I think it's smart of Marvel to release the look in a trailer up front so those folks have time to get used to it, at least.
With Spider-Man returning to the MCU he HAS to have a different look from the Raimi or Webb films and there's not much different you can do with the existing look unless you go retro. And, by going retro, we also have really the first truly young superhero which is another refreshing change of pace. This costume makes sense on so many levels and is something I appreciate.
