Review by oyuksel

I see many viewers considered this chapter too confusing. Note that even in the earlier 1963 episodes, time loops were too confusing for viewers where we see those as trivial these days.

The concepts introduced in this chapter and added multiple layers of flash back-and-forwards might strain thr mind a bit. To see the value in those, just keep focused sharp, do not fiddle with your phone and breathe calmly. Pay attention to the environments and accents. It shall become clear to you and you will LOVE it.

I strongly believe that this episode/chapter leads to invaluable future expansion of the Doctor Who lore.
