I am not offended of course, but I don't think my post is nonsensical at all.
It's probably a bit dismissive when it comes to the possibility of this guy finally writing a good script, but I find that within reason, given that this little work he did so far is not very convincing. He might be a solid writer that just hadn't a chance to shine yet, but, unlike the opposite opinion, I have nothing to base this on. At this point, my doubts when it comes to his abilities as a writer and dissatisfaction with this choice are justified.
Still, when it comes to films, writers are not positioned very high in the hierarchy for a while now and, more often than not, directors are the one that call all the shots nowadays. I usually find this to be a shame, but in this case, as I already said and you mentioned it as well, it might prove to be a saving grace.
