Wow! I love this IMAX artwork for Rogue One... I think this was possibly the most creative promotional work for Rogue One!
As for which I preferred, I'm going to have to go with The Last Jedi. The Last Jedi had some structural weakness' as a film- but I really have to applaud Rian Johnson for delivering on a film that was atypical of what I would have expected from a Star Wars film. The Last Jedi didn't have much of a reliance on nostalgic imagery (with the exception of the AT-M6's at the end on Crait) and for what it's worth- The Last Jedi wasn't heavily reliant or dictated by where the Star Wars Story "needed" to go.
Thank you, @Wreck for the great giveaway of such a beautiful Fullslip!
