I gave this one a 9. It felt like a Trek episode, and actually had good character moments in it. I like that they explained via dialogue and short recall clips the numerous loops, as opposed to TNG's "Cause and Effect", which felt tedious to me. Maybe I'm warped, but I liked the clips of Mudd killing Lorca, culminating in the one stranding him in space. Also, Mudd eating a sandwich in the Captain's chair had me laughing.
There were some nice background bits in the After Trek episode, such as the design of Mudd's helmet, and how multiple takes had Rainn Wilson using different nicknames for people (save for Lorca, who he kept the same nickname to annoy Jason Isaacs).
And, this was the first time in a DSC episode that I could actually pick out parts of the incidental music! The recalling of the TOS fanfare when the Baron's ship moves away from Discovery was really nice.
I enjoyed the episode, suspended disbelief and just enjoyed it.
