Now, the concept of ranking anime programs via tiers is a pasttime of the people on 4chan. Well, actually, they do it with various types of media, and even people and music. Usually tiers lead to a lot of shitstorms, though, and generally tier threads are (and should be treated as) troll threads. Tier threads are absolutely awful, mostly because the rankings go unexplained and they lack the nuance of a more ordered numbering system. Still, those tier charts are tempting to attempt.
So, with Gundam anime, I've decided to compromise, and try my hand at one of these things, but also provide reason for my decisions as to where to rank each entry. Now, as I have yet to finish watching some of these, or haven't watched one or two for a long while, the list remains "open" to a degree. There's some possibility for mobility, as well as reconsideration for most of what's on here. So keep that in mind when you're reading this.
Tier charts are usually divided into a few different tiers. Here I've divided it into the popular ranks of "God Tier", "High Tier", "Mid Tier", "Low Tier", and "Shit Tier". "God Tier" being the tier in which, in my opinion, the best Gundam anime are in, whereas "Shit Tier" has the worst Gundam has to offer. Since I enjoy ending on a high note, let's begin with the worst of the worst, the Shit Tier.
I wanna have a pure time. Everyone's a noble mind.
There's no doubt that I'm a fan of the Gundam franchise. For years, I've watched the programs, collected the DVDs, downloaded the pictures, read the notes, and pieced together the models (though, poorly). I've immersed myself in the world of giant robots, angst-ridden teen pilots, colony drops, and downer endings for quite a while now. I have definite opinions on mechanical designs, plotlines, and alternate continuities. I'd like to think that most of them are well-informed by my experiences in Gundam fandom.
I must have no life whatsoever. I need a girlfriend, or a job, or something. Because I just spent nearly an hour arguing about what is and what is not canon in Gundam's Universal Century timeline.
The Universal Century timeline, by the way, is the original "universe" in which Gundam takes part in. The original series and its direct sequels (Z, ZZ, CCA, F91, and V) take place here. Also, several side story OVAs (0080, 0083, 08th MS Team, and MS Igloo). Also, there are several video games, side story manga, and novelizations. However, Sunrise has claimed that "if it's filmed, it's canon".
