For a long-time cranky old man refusing to do sequels, Ford is now showing up in a lot of them, playing the old, tired, and cranky version of his former iconic self, training a new protege.
Not much seen in this, but it looks OK...possibly because that trailer doesn't show anything beyond the now all-too-familiar "Harrison Ford re-hashes a legendary character from his youth and looks really weird doing it" scene.
I hope it's good--BR is phenomenal--but going beyond the Dick story, I don't know (not that BR had all that much to do with the original story anyway....).
