lol, it's like if the original trilogy started with ROTJ and didn't tell you why they needed to rescue Han or anything else
There has been nothing so far to say who Ezra is, why he's important (both to plot and characters), how he got where he is etc
Even now, they're only just explaining to casuals the backstory of Ahsoka
It's not like the backstory of what you're looking isn't readily available, go watch Rebels.
I can see why a show targeted at 9 year olds is appealing to you.
So you're investing time complaining about a show targeting 9 year olds?
