Just got back from the cinema - really loved it!
There isn’t much I’d change really, other than introduce a crawl, and replace a number of the opening scenes with just exposition from the crawl.
Personally I’d like to have a version where you would view it prior to the OT, so numerous ‘reveals’ that relied on seeing the trilogy first (and obvious cameos) could be toned down or changed (or removed).
Vader is a bit over the top I felt - but I really enjoyed his part.
CG Tarkin was great - CG Carrie Fisher maybe less so.
