Even later here but I've finally seen it!
I found R1 to be a really good film overall. I need to see it again to give a final verdict but yes I enjoyed it.
Admittedly at the start I wasn't sure, especially with all the movement from one planet to another (with the badly done location text) but I settled into it and after 30-40 mins I felt like I was in the Star Wars universe once again.
The rebel characters were all really good, I thought Jyn and Cassian were great characters and K-S20 gave some much needed comic relief in the form of his dry one liners. I liked Chirrut and Baze too, the chemistry they had was fun (and sad at the end) and the ass whooping they gave to the Stormtroopers was great too.
Tarkin CGI could have gone really badly but I actually enjoyed his scenes more than I thought I would. I bet we all thought the same thing the first time we saw him on screen "uh oh, this is going to be x-box cut scene material" and indeed that first scene was a bit ropy but the rest was fine and I enjoyed exploring his character a bit more than we saw in ANH. I quite liked the way he just took over Director Krennic's DS operation (or tried to) after the first successful test, very dog eat dog and also quite fitting for high ranking officers of the Empire.
I wasn't sure about Krennic when I first heard him speak at the start of the film, his accent was a bit odd (is the actor Australian?) and his lines were a bit wishy washy, kind of like how some people reacted to General Hux in TFA. Still not sure if he was worth the hype, at the moment I would say no but we all know he wasn't the real Villain anyway and Vader's appearance at the end didn't disappoint for me.
Vader's castle was ok, I get that they wanted to revisit an old McQuarrie concept but I guess in my mind I always kind of see Vader as a character that has no real home. In the OT he's either on a shuttle, on a Star Destroyer or on the Death Star and just visits planets or cities on missions, he's kind of always in motion and just floating around wherever the Emperor sends him. It was cool to see him in his bacta tank thing and the little chat with Krennic was alright but I didn't think it was amazing. IMO the best Vader scene in R1 was him just totally destroying the rebels on his own at the very end, the brutality of it all actually took me by surprise and I can't wait to see it again a few more times.
First watch 3.9/5 - happy but want to see it again and will gladly do so
