Admittedly, these series could be potentially great. They are not as polluted with the PT as CW series.
But from what we got so far, I hate the main villain because he is another force user and an alien on top of that. They always try to stick some secret apprentices (idiotic Starkiller etc.) and force user minions under Emperor and Vader. I just can't stand that. On other hand, I dislike seemingly the main hero (this Kanan) because it is obviously an awful copy of Katarn and I think he looks dumb too.
In an ideal world, two main villains would be a high-ranking imperial officer and his top operative (sort of an Imperial Agent from SWTOR type of right hand man/woman). While the main hero would be a young rebel with no force sensitivity. But that will never work because the kids want to see the kind of crap they are making now.
