Best marketing campaign ever for Deadpool, I've said it multiple times, props.
Of course directors have a vision, but the inference that Marvel Studios doesn't allow directors to have any is bogus. They've had issues with creative in the past, LIKE EVERY OTHER STUDIO, but my point is they've had a vision and respect for their characters (and bigger universe) right from the start, which is where they differ from others. Obviously helps if there is synergy from top to bottom.
It's a good thing that Fox won't try and put Deadpool into a larger cinematic X-universe in future films. We don't need his uniqueness bogged down by bloated corporate concepts.......
