I agree, which is why I say just to continue the series with the son, or new stories. Don't remake the original. I also stated that Walt himself did re-use characters in other stories.
As for the Indy stories, it is good to remember that Raiders of the Lost Ark itself was a throwback to the old moviehouse serial shorts that ran in the '40s before the feature. So, in that way it can be said that it is intentionally like a big-budget, feature version of old serial shorts.
I guess the discussion can turn on, for new stories, would it be better to start where the orginal series left off, perhaps with the next generation (or even older Indy); or to recast and use the same characters but for different stories altogether. Maybe that is what they meant by "reboot," but I was originally rebelling against it in the framework of a remake, like the superhero movies have essentially been when they "rebooted" a "franchise" (clearly terms that the accountants liked more than the creative people).
