I think that the main problem with having an opening crawl is that you DO NOT start with the prologue clip (Lahmu).

That is the major mistake everyone seems to be making. And it certainly was not the original opening shot to the movie. It’s a lame opening.

If you have the opening crawl and then open on a shot of the Dish being fitted (Seriously this is a wow factor sequence) on the death star then all the problems are solved. Although Jyn is the main character and Galen her father is helping to build the Death Star. They should not be mentioned in an opening crawl. They should not be focused on what so ever. Only the Broad themes of the Republic the Empire and the Rebel alliance.

The opening prologue is just a flashback and it should not have opened the film. The Death Star Dish being fitted is of the caliber of an opening shot though.
