It’s pretty solid! I dreaded watching it, when I first get around to it and after watching it, admittedly I don’t understand why this story is really looked down so much, sure it might be perhaps one of the weaker ones in this Season for me but honestly, it’s really solid. I think the pacing is alright, I always love a good 6 Parter and while this by no means is a perfect one, it doesn’t really drag like some other stories do. The Cliffhangers we get here are fairly good, with the standout being the first one. The build in suspense in the first Episodes are stellar, seeing the Doctor doing actually Science is great and of course as many pointed out this is pretty much one of Susan’s finest hour we got in the Show. I do think some plot points around the end of the story just kinda come out of nowhere and while not a bad idea, they do kinda lack the fleshing out.

But overall not really bad, not a personal favorite but yet another strong outing for Season 1!
