So I was a complete Gundam tourist until ep 10 and yesterday. I just finished watching up to ZZ, Zeta compilation movies included, and I pretty much regret it.
I thought watching the previous series would made me like Gquuux more or appreciate it more or justify the episodes until now but it pretty much did the opposite.
It didn't have anything the previous Gundams had to offer except for mountains of clapbait references.
OG was awesome, Zeta was pretty dark and suffering but pretty damn exciting, ZZ was goofy, enjoyable as fuck, but still managed to become dark and serious later on. Gquuux had NONE of these.

I pretty much know the ending of CCA so I haven't watch it yet.
