That was fun.

Might've been the most solid episode of the new era, BUT... it was too much, literally.

I know it's kind of the point of the story that they all tell their stories, but the "Tell not show" really didn't work when it came to explaining the cosmology. Just on words it was too much and it had me disoriented.

Omo was a fun character, but I wish we had a little moreflashbacks of the Doctor visiting the shop, because then the scene of him being angry at Omo because he trapped him would've made more sense, while now it felt random and a little hollow.
Add to that the cameos that felt desperate, as if they tried to win us with fanservice -while the Fugitive Doctor appearance sort of made sense, at the same time it shot itself in the foot because the Doctor isn't supposed to remember their life as a Fugitive.
Overall, the almost perfect episode that just needed trimming down (pun intended) to not feel overstuffed. The idea is amazing, don't get me wrong, but it is too vast for such a short period of time.
