Maybe it will be good, I like Rebels and I'm looking forward to the seventh season of Clone Wars but honestly The Last Jedi was a real let down for me and as of right now most of the films just feel like their simultaneously trying to recapture the glory days while also trying to one up them and prove how much better this new era is... only for that to come falling down when all they do is feel like hollow copies of Stories that where, IMO, done better in the Legends continuity.
Rouge One, Kyle's story was more engaging and Kyle himself is much more memorable then most of the characters in RO. Solo? While convoluted I much prefer Han's backstory that we got in the Novel Trilogy that focused on him while the resent film honestly felt more convoluted then what we got in Legends. The Sequel Trilogy? The Thrawn Trilogy is still considered a classic that revitalized Star Wars and it's influence on the series and Pop Culture is only matched only by the Original Trilogy while I honestly wonder if The Force Awakens and The Last Jedi will really stand the test of time.
Please note I liked Awakens when it first came out and I was willing to forgive most of it's flaws as the sequel could address them and help flesh out the story. Instead we got Last which was more interested in subverting everyone's expectations in ways that I felt was rather stupid as the surprises are only surprising because it doesn't fit any of the characters from the original Trilogy or even the newer films.
And on a side note, given how similar the characters are between Rouge One and Rebels how much does anyone want to bet that RO was the intended series finally of Rebels before someone found the script and decided to use that for the first anthology film. I mean wouldn't that make more sense if the characters we've been following for however long Rebels was suppose to last that it would end with them going after the plans for the Death Star. In fact I also wonder, given how similar the two look, if Ezra was suppose to be Kyle and at the end of the series he would change his name or briefly use the name Kyle Katarn to show that he was a Canon Character All Along.
Silly fan dream? Maybe but I like the idea.
