Ok, I read a ton of negative reviews and found flaws in the gripes. Most sound like casual fans that don't know Star Wars well. So I think the heavy Star Wars fans liked the show and the Star Trek people didn't.
My favorite Negative review so far was "Boba Fett's voice is not the same as it was in the movie, 1 star".
The actor who did Boba Fett's most famous line of dialog misspoke the line. When he said "Put Captain cargo in the Solo hold". So even though Boba Fett has only four moments of voice dialogue, consisting of five sentences it was done by two different people.
What voice are you talking about? Of the three Boba Fett's voices out there I can't narrow it down to less than two based on your complaint.
I respect that your remembering the original voices after all this time but still there are two of those. "All this time" because You hear Temuera Morrison's voice in the remakes of the old movies now, as it has been redubbed over the other two.
You never hear Boba Fett's voice without him wearing his helmet in the original trilogy. With the original two voices, there are many reasonable explanations for why the "True voice" of Fett that you remembered was not the same one we hear after the bath in stomach acid of the Sarlacc pit as to make this a totally frivolous complaint. Yet that user ranked the show 1 star based on that alone.
