As for the second half of the fifth episode (Princess on Lothal), I felt like it cut WAY too much and made things move WAY too fast. IMO Leia’s little introduction aboard the ship (0:46-2:00 of the original episode) was much needed, otherwise we just have a legacy character randomly popping out at the scenery; also, it’s important in-universe 'cause it shows the Empire is very tired of Alderaan meddling in their affairs, which makes them going after it on EP IV a little more believable. Also Kanan and Ezra talking to Leia before facing off against the stormtroopers (6:05-6:50 of the original) was also quite important, not only to keep the pace a little slower but to give some more background as to how Alderaan and the Senate can keep supporting anti-Empire stuff. And for last, the cut pep talk between Leia and Ezra (10:54-12:19 of the original) was a pretty sweet moment of character development for both of them, I don’t see why leaving it out.
