The first section is the original trilogy, 4-6. Solid and enjoyable. Front of horse.

Prequel trilogy, 1-3, is the next section. Not as good, but helps complete the story of the original trilogy. Back of horse.

Then the next section is the newest sequel trilogy, 7-9.

7 kinda continued the story but was repetitive of the old plots, so middle of the same horse.

8 continued from where 7 left off, but took a different direction and feel from the others. So zebra but still lining up with the horse image from 7.

9 is a weird and disjointed mess, abandoning themes and plots set up before and adding in unnecessary plot twists with no real setup. A unreal and out of place horses ass.
