Star Wars - Rogue One

Walker of Rogue One

Watched Star Wars Rogue One yesterday night.

As a person who had watched every episode of Star Wars since 1977, I find Rogue One enjoyable. Memorable parts include:-

(1) Darth Vader who was dead in Part 6 was alive in Rogue One. Love it when he uses the light saber
(2) All the familiar original X-wing and Tie fighters. Space fights scene was good. The use of aiming mechanism onboard Tie fighters is a reminiscence of the same used in A New Hope.
(3) Director made the security facility (internal) in Scariff looks like the original Star Wars Death Star
(4) The original storm troopers
(5) The original star ship and fleet
(6) The original Imperial walkers (from Empire Strikes Back)
(7) Admiral Ackbar and its space ship
(8) The connection with Star Wars A New Hope where the last part of Rogue One is the beginning of A New Hope. Awesome connection.
(9) A relatively simple story

What I hope can be improved:
(1) Digital animated actor like Princess Leia and Tarkin is unreal, but good effort. Rogue One use of animation (or rather the less use of it) is still better than Star Wars Part 1 (The Phantom Menace) battle droid, which is totally artificial. The K2 unit seems realistic enough but could not recall the presence of K2 unit in A New Hope.
(2) Why would the top of the security facility has openings that allows human size droid or person to go through. Isn't that a security breach? Ventilation duct should not be opened in the first place.
(3) Strange that Rogue One is multi-racial but A New Hope does not reflect that. Obviously for commercial reason.
(4) There are birds on another planet far far away from Earth? Most of the Planets are quite earth like other than Darth Vader Planet Mustafar.
(5) The storm troopers vehicle on Planet Jedha is basically an earthly tank. Could have been more creative in imagination. Something which Star Wars Part 4 to 6 had achieved.

Lastly, Rest in Peace Carrie Fisher (aka Princess Leia).
