Just started this today, and have seen the first four episodes.
The first two truly are a little clunky. But I doubt its possible two make any them better, when the source material is what it is. The Duchess of Mandalore was a treat tough, but Assassin was OK at best.
Looking forward to the rest, I guess it will only get better now that the introductions is over with.
On a side note: It’s interesting to first watch the episode and then to read the posts in this thread discussing it.
