I just don't get it.  For a cast this interesting and for a combination of characters this fun, I really expected to enjoy myself a lot more than I did.

The biggest issue is definitely that we have the fun of the Ninth Doctor, the Lumiat, the main Unbound Doctor, and Liv all in one story, yet they spend a lot of time split up with each other.  There isn't a lot of fun interactions here besides a couple of fun moments between Nine and the Lumiat.

Additionally, the whole idea of the Time Lord Immemorial sounded very fun as a concept, but completely underdeveloped and not fully explored as an idea this big should be.  I'm a sucker for legends and myths in Time Lord culture, so I would very easily enjoy a story like this if it did ANYTHING with the concept.

It doesn't help that this is one of those audios that really highlights how none of these characters can even remember these stories because they mess with continuity so badly.  I feel like the better chapters of Once and Future skirt around that while Time Lord Immemorial accidentally just highlights how pointless this anniversary special feels at times.  There's some fun scenes here and there but overall it just doesn't come together as a satisfying narrative.

This is the first Christopher Eccleston audio I have listened to, and I prefer his Doctor here. On TV, I felt he was too serious, which made sense narratively given that he had just survived the Time War, but it didn't make his Doctor much fun. Here, however, there's more of a lightness to his incarnation, as he is not burdened by the Time War. Christopher Eccleston is also a lot of fun alongside David Warner's incarnation, with the pair developing a great rapport.

The story itself is an exciting listen,  concerning the multiverse falling apart due to the sands of time running out, and a God known as the Time Lord Immemorial. It feels like a curious mix of a 2005 story and a classic series adventure, with the Time Lord Immemorial feeling similar to other Time Lord Gods such as Omega.

The alternate universe Doctor interactions are incredibly wasted potential, but I can’t be too mad considering the Thoschei content we got.

I thought it fun. Nine realizing Lumiat was the Master was a great moment. I love the silly time lord legend. Actually it was mostly Nine and Lumiat doing anything that I loved. I can’t come up with more well constructed reasons, sorry.

Also, interesting that the degeneration changes the person so much to that certain incarnation. It’s not just the body changing, but as we see with the Lumiat, the entire personality and way of thinking as well (which made for that really great ending where she was holding herself back from becoming the Master again). Curious if that is gonna be expanded upon.

After some fresh air from the Martian Invasion we go to... this...
Good grief...
I am disappointed.
Seriously, how could you waste such a potential of colliding the Doctors from different universes?!
The chemistry between the Ninth Doctor and the Unbound Third Doctor here is almost non-existent - they just bicker for some time and after that discuss the Time Lord Immemorial prophecy.
Liv and the Lumiat are just there, I have nothing to say about them.
Christopher Eccleston was great as the Doctor, but late great David Warner... for some reason he sounds nothing like himself, and he didn't do much and felt out of character. Which is a shame, since this Doctor has A LOT of potential in meeting the N-Space Doctor, but here he is present just for the sake of it. Swap him for Martin!Fourth Doctor or even David Collings Doctor, and aside from a few lines nothing would change.
And the Time Lord Immemorial... eh? He just sits there. And his prophecy is said to be very important, yet I'm pretty sure it won't be referenced ever again.
This was the story for which I was excited the most in this anthology, because I LOVE the Unbound Doctor and I always wanted to see him together with the N-Space Doctor. And when I found out it was going to be Ninth Doctor - the one who brought me into this wonderful series, I got even more excited.
And now... the potential is wasted miserably. I had fingers crossed for the next one.
