I've always like time loops and this one, though ragged, has some things going for it. Harry Mudd is seeking profit and revenge. Through some kind of technology he has managed to get into a loop where he will discover how to take total control of the Discovery and sell it to the Klingons. I guess the problem is the number and intensity of the crew and the fact that it is a very complicated ship. To all the Onesies, don't you ever just have fun watching something without totally dissing it. There are good actors, a fun plot, and a look into the soul. Embrace life a bit.
