Good? No, but it's not bad either. It is very weird. Most of it is meh and forgettable, full of nostalgia baiting, which is too be expected from Disney's Star Wars. It also is full of good character portrayals by Ray Stevenson, David Tennant, Lars Mikelsen, Claudia Black and more on one side. On the other is literally some of the worst acting I have ever forced myself to endure in my life by Natasha Liu Bordizzo. Mary Elizabeth Winstead and Rosario Dawson weren't great but at least they didn't make me want to throw my shoe at the TV. Another painfully bad thing about the show is the dialogue. Whoever wrote some of the dialogue really needs to reevaluate their career choices.

On the plus side, it has some of the best light saber fights you'll get to see anywhere.

So, overall it would be a passable yet forgettable show were it not for the bad dialogue and terrible acting (by some).

Kind of too early to tell. Season one was heavy on setup. I personally enjoyed it. You really need to be familiar with The Clone Wars and Rebels, though.
