A lot of characters played important and long lasting roles in the Clone Wars, and that large and varied ensemble cast made it something special, but in the end it was Rex and Ahsoka's show. Omega is the Ahsoka of Bad Batch, and I would wager that Hunter will be her Rex, but Echo is a much more interesting character and I hope it becomes him in the end.
I'm not so concerned about the show getting stuck in a cycle of Omega getting into danger and having to be bailed out constantly. Clone Wars saw Ahsoka start out similarly and look at the badass she became. These people know how to develop a character and I'm looking forward to seeing who Omega becomes.
Right now I'm a little frustrated at the sheer number of veteran Clone Wars cast members returning. It isn't too shocking, given that this might be our only chronicle of this period outside books and comics and, I suppose, games now too. But it does lend this season a real "status update on old friends" vibe, even if it is super cool to see them all again.
The Book of Boba Fett has apparently wrapped filming.
