It would have worked so, so much better for me had it been a much simpler, smaller scale heist type movie with zero cameos, and Jyn would have been a much more interesting protagonist had she been, as early trailers seemed to indicate, a thief/criminal recruited into the alliance, and not directly personally connected to events and also sort of kind of a rebel soldier but not really?
It's got that Hobbit problem for me where they wrongheadedly try to top the scale of the original movie in the prequel. Why does EVERY SINGLE blockbuster now have to end with 30 numbing minutes of explosions? After a while its all just noise to me.
