Somewhat off-topic, but this problem of repeating origins could be painfully seen in the Amazing Spiderman. Now, in many aspects I think that movie is actually surprisingly good - I had heard it was bad but it seemed nearly on par with Rami's first Spiderman movie (it seems there's a lot more problems with the second film - the visual design for the Green Goblin in particular is... poor).
However, it has a big structural problem in that too much run time is taken up by the origin. While it might have meant missing out on some good scenes with Gwen, I felt the intro and origin could have been rushed (as the audience understands it) and to get onto the new stuff - the background with Peter's father, Connors and Obscorpe, more around Gwen, more resolution for tracking down Ben's killer etc. - that would have made less of the last hour of the film feel like a rush, and to give space and time to breath.
Having the origin of Spiderman done in film for Rami's first film was an excellent idea; it really didn't need to be done again even with the differences in character, as the MCU's Civil War and Spider Man Homecoming proved.
Which is why the fact this film seems like it's going to skip all that origin stuff - or go through it very slightly - is so god damn blessed. It's been done twice; it really doesn't need to be done again.
