I really enjoyed it....very gritty, not the usual Star Wars affair
I loved the Vader scene in the end!
The detail in which everything had the look of the old environments, from ships to the interiors, clothing etc.
Saw no trailers or read nothing about this beforehand so was genuinely shocked to discover Tarkin was CGI...I dunno maybe im a bit simple but looked real enough to me!
I liked the battle at the end.....finally getting to see the old ships in a proper star fight and for it to not all be nonsensical but there to have a genuine build up to everything that happened, leading to the final scenes where it tied in brilliantly to a new hope.
Maybe it dragged a bit in the middle and I don't think I cared THAT much about the main character and the emotional side of her story....but that's my only small gripe.
Don't think the film ruins the series in any way, instead it brings in something a little different but still high quality
