On that note, that’s one of my many gripes with Star Wars Rebels. Every episode ends in mission accomplished with no casualties for the rebels, thus making the victories of the OT a lot less impactful.
I’d guess you’re against the show existing at all then. You can’t exactly tell a story about the gradual formation of the Rebel Alliance by showing them getting crushed and defeated at every turn. There were always going to be small victories, the events of the OT and Rogue One are just the first major victories.
I’m not saying the rebels should have been crushed and defeated at every turn as you put it, but the fact that they never suffer any setbacks makes the Empire look incompetent. How about two steps forward one step back, then three steps forward one step back, four steps forward two steps back, the Rebel Alliance slowly gaining in strength, occasionally throw in a defeat that sets the Rebellion back from square 50 to square 35, certainly damaging but not enough to erode their determination. It would have made for a much more compelling narrative than the smooth sailing of victory after victory we got.
