I would have loved to have watched a 3D version of this on the big screen, as PROMETHEUS looked excellent in that format compared to certain other 3D releases.
While I've certainly got many issues with ALIEN COVENANT (and plan to re-edit it more to my liking along with PROMETHEUS), I know that many of Ridley's scenes would again have looked terrific in 3D.
For instance, GRAVITY had some of the most involving and effective 3D I've ever seen, and I kept thinking how good the COVENANT 'spacewalk' sequence would have looked in that manner too.
