Finally had a chance to sit down and give this a watch. Wow! I knew this was going to be good, but not as great as this.

A few thoughts -

At no point did it feel like anything was missing. Obviously I knew what had been cut out, but the seams were pretty much non-existent.
I personally feel like the original introduction of Mando works a little better than just seeing him being rescued by Kuill on Arvala-7, however I see where you were going with it.
In removing the Tatooine episode, you have omitted the ending scene in which Fennec is rescued by Boba Fett. Will this scene be included in your Season 2 edit, or will it just be assumed that the two have always been travelling together?

Other than those two queries, this is pretty much the best way to watch Season 1 without all of the fluff that held it back the first time round.
