Review of Fate/Grand Order: Absolute Demonic Front - Babylonia

Fate/Grand Order: Zettai Majuu Sensen Babylonia or should we call it Fate/Grand Order: Deus Ex Machina? First things first. Spoilers ahead. Spoils will focus on the last third of of the show. Don´t get me wrong. The first 2/3s were kind of enjoyable. You fight the alliance of three godesses to safe Uruk. During the episodes you get the usuall treatment. Some charakters die, some switch sides and now help the protagonist etc. During the "final" fight against Gorgon aka Tiamat, Ana reaveals her true identidy, kind of, and makes the biggest sacrifis and dies (?) and so does Merlin. Or at least the both vanish. Butoh shock. Gorogon wasn´t the final boss. It is the real Tiamat. And oh boy now the show turns south.

So the real Tiamat joins the scene.She has the Holy Grail now. Sure thing she is even more powerfull than all the other before. Thank god she is out in the sea and takes several days to reach Uruk. How convenient. This means our party can create several plans to stop her.
First plan. Fly directly to her and let Ishar blast her away. And it worked, or did it? Sure it didn´t. Tiamat comes back in a even more powerful form.
Back to drawing board guys! The black stuff Tiamat creat seems to be the key. If we destroy it Tiamat can´t move and we can send here to the Undearworld and defeat here. How? Let´s just use Quetzalcoatl´s Noble Phantasm and it is done.
So Quetzalcoatl does the things. Black stuff destroyed Tiamat badly damaged. But Quetzalcoatl seems to die in the process, or did she?
Anyway. Black stuff is destroyed and the monster can´t move now. But oh boy the monster starts to grow wings now. Thats a bummer. All hope is lost. It doesn´t need the black stuff anymore and when it can fly it wont fall into the Underworld. But thank god Gorgon shows up.
Wait, Gorgon? Yeah Gorgon. The boss which was defeated several episodes back shows up again. But now it is not Gorgon it is Ana. Sadly she doesn´t stand a change against Tiamat. But at least the wings are destroyed and the monster has to walk again. Underworld plan still possible. Yeah!
Tiamat is now in Uruk and needs to be sent to the Underworld. Gilgamesh gets hit and is about to die. But Enkidu, which is good now, joins the battle. Uses all his lifeforce and sends Tiamat into the Underworld.
Finally in the Underworld. A place where Ereshkigal reings and Tiamat can be defeated. And it seem to work. But remember the Black stuff? Yeah it is back and Tiamat wins the upper hand again. How convenient Merlin shows up again. But not the Servant Merlin. The real Merlin this time. At this point I was like OK, what ever.
They start winning again. But Tiamat evolves once again into a even stronger Monster. This leads to the question. Is she a Pokemon?
Since Tiamat became stronger once again we need another protaconist to show up to help. This time it is the "old man" aka Ziusudra. But the fight still can´t be won.
But it would be Fate Deus Ex Machina if not another hero would show up to safe the day. I wonder who is it this time. *drum roll" It is Gilgamesh! Yeah he is still alive! No he isn´t. Because it is not the King Gilgamesh but the Servant Gilgamesh who felt like to join the party.
And after bringing all dead charakters back to help they finally win. Yeah.

Last episode. Quetzalcoatl shows up again. Yeah I know. What ever. And so does Jaguarman, which was totally forgotten by the plot. Time to say goodbye.
King Gilgamesh shows up again and gives the MC the Holy Grail. Which everyone had forgotten by now. Gilgi safes the day once again.

Gosh the last 6 episodes or so where so hard to watch. Everytime they seem to lose another "dead" charakter shows up to help. It became just silly.
How can anyone defend such a bad Deus Ex Machina Plot? How is this rated 10 by some guys here?
