I liked it, the Clone Wars war announcer VO at the start was a great way to begin the series, even though I only watched Clone Wars a few months ago. Must have been amazing for anyone who watched it while it aired, since its been 8 (!!) years since Clone Wars ended.
Obviously the Omega character is super wonky, but its a stand in for kids watching the show to identify with someone so makes sense. I'm guessing she has midichlorians or some shit, Jango Fett's dream and nightmare of a jedi daughter lol.
The only bad plot point I thought was Admiral Tarkin being in the episode, it makes zero sense that a dude like that would jet off to the clone production facility on day 0 of The Empire. All the admirals will be fighting to make themselves the Emperors right hand man, hunting down jedi and remnant seperatists. Him focusing on 5 clones was really silly, it shoulda been a lower ranked imperial.
I really like the time period, day 1 of the new Empire and it shows the kind of flex Filoni has now if he is being given the story reigns of such a critical time period. I hope we get some Vader hunting Jedi.
