Yeah, I hate to contribute to this train-wreck of a tangent, but seelsa73 nailed it. You are making great efforts to phrase your complaints like level headed remarks, but consider for a moment the claim that you are the only person here presenting an objective and mature perspective. That is in fact a pile of grade a **** by the definition of the word objective. The things you are stating are OPINIONS. Any and all opinions about entertainment are 100% subjective. You are perfectly free to hate Rebels. I really couldn't care less. If you want to share those dissenting opinions, feel free to do so as well, though I'd expect some negative blowback given its generally positive reception in fandom. But however you feel, at least have the intellectual honesty to say they are opinions. If you try to turn them into objective fact, we end up with a derailed thread like this. Maybe if you gave specifics about why the tone doesn't feel right to you, then a discussion could have started, but instead you opened with beating the same internet dead horse about how one of the characters in an ensemble cast bears a superficial resemblance to a character from another franchise so Star Wars has been defiled. (not even going to go into why the connotation of that statement may have set people off as well...) Anyway, just some things to consider if you are in fact not just trying to get a reaction and decide to revisit this thread.
Back to the actual point of this thread, I thoroughly enjoyed Rise of the Old masters. The way they turned a joke in the beginning into a poignant moment at the end was fantastic. The team seemed to work effectively on the mission, I like the way things turned out with Luminara and there was a neat EU nod and an new character who I think may be EU inspired. Over all a really solid, fun episode to watch. The only thing that bugged me was that they escaped essentially because the Inquisitor was lazy and toyed with them for too long, but I'm sure he won't make the same mistake in the future.
