For the season as a whole, I kinda put it at maybe a 6.5 or 7 out of 10. I enjoyed it, but it suffered from production, editing and money issues. Amazon really should have given it more money (and good news, season 2 is getting more, yay!) Also, apparently the show-runners lobbied for a 1.5 or 2 hour premiere and 10 episodes, and I think a lot of the story-telling issues would have been a bit easier with a bit of extra time. (And a few better choices in what stories they NEEDED to tell in the first season).....
The story was too complex and there were too many characters.
I recognize there is a need to appeal to hard core book readers and long term fans, but The Mandolorian, for all it's flaws ( it's not perfect), does a very good job of taking a relative simple plotline and breaking it down into manageable chunks that focus on practical world building. Favreau and Filoni did a good job understanding the main character is simply a vehicle to highlight how everyone else interacts and reacts to him in conflict.
Complex characters inside a simple storyline will always win out over an extremely complex plot and narrative with painfully simplistic characters moving like pawns on a chess board.
If you look at the Netflix/Disney Marvel shows, the villains should be the ones with their own shows, and not as foils for pedestrian hero characters. Kingpin, Cottonmouth, Kilgore, Zemo, etc, etc.
Shows without commercial breaks have zero excuses. JJ Abram's Lost had some real narrative problems on it's own, but the network TV format ( 42 minutes with commercial breaks and an extended recap to start, with the traditional teaser and need for a mini cliffhanger to end the episode) pushed the writers further into a corner.
Snappy witty writing isn't as useful as efficient writing. Efficient writing is taking a short scene and doing 5-6 different things at once. Michael Corleone waiting for Frank Pentangeli to come back and talks about how to keep your friends close but your enemies closer accomplishes 7-8 different things for the overall narrative.
Things that will help
1) Establish the main villain early and keep them involved and invested. Formulate the viability of the threat in place for the main characters. You have to get a charismatic actor and let him chew the scenery as your "Big Bad"
2) You have to give the main characters an intermediate goal as season long arcs. Give them a conflict to overcome so they can organically develop , even if that breaks canon
3) You have to establish the rules of the world. The first time audience doesn't know the limits of Moraine's power or what she can or can't do or why or when or how.
4) When you have newish limited actors as your main cast, you have to give them "anchor traits" BA Barracus refuses to fly but he loves milk. Face Man loves women and is a grifter. Murdoch is the insane pilot. Give them each something unique to overcome ( like the Wizard of Oz)
The pandemic probably hurt the overall process, but this first season was quite sloppy. When you have a lot of things working against you, simple is always better. Z Nation was infinitely more structured than The Walking Dead despite probably having 1/100th of it's budget and 1/500th of it's actual raw acting talent. Z Nation had a rag tag group trying to get one man across the country alive. Simple. Walking Dead just meandered from one recycled nihilistic plot to another. WOT could have done more with the money they did have.
There is a larger question whether this show would have stood a better chance just being fully animated and operated like prestige animation ( i.e. Attack On Titan) Some stories require too much for a practical live action budget to cover and handle.
