IIRC, Logan's script for "The Gladiator" was so bad that Russell Crowe insisted on changing a bunch of lines which he considered too stupid to say on screen. William Nicholson was eventually brought on to do a thorough rewrite, which got them an Oscar nomination.I mean I didn't like what Logan did with Nemesis working alone, but he's worked with Purvis and Wade on Skyfall and for the most part it's worked out well!

He must have some talent/be good for something given he's apprently still gonna be on the team for Bond 24. Maybe he makes a really good cup of tea? Or maybe he's good with plot and bad with dialogue?
