Except, again, Johns didn't write any of the scripts for those movies. Zack Snyder's Watchmen is nowhere as good as the original comic. Is Alan Moore to blame for that? Man of Steel drew from All Star Superman and Morrison's Action Comics run. Is Morrison to blame for that movie not being so good? And BvS was directly inspired by DKR, one of the best Batman stories ever told. I suppose Frank Miller is to blame for that movie being an absolute dumpster fire.
