Between these 2 follow up seasons, which one do you think is the worst? Mobile Suit Gundam SEED Destiny or Iron Blooded Orphans Season 2? I can at least say Destiny has…a story… that's more than I can say about IBO S2. While IBO S2 doesn't have a whiny bitch of a protagonist. I genuinely can't express how equally I felt equal amounts of frustrating hatred towards both of these shows. I guess it's a matter of being mad at a series that could've improved upon its predecessor or mad at a series that spits on everything great about the 1st series, which…. let's just talk about what's wrong with each show individually:

• Destiny: Both shows had trouble productions, but I think Destiny had it way worse. After the success of SEED, Bandai/Sunrise demanded a follow up to the series. With NO PRE-PRODUCTION, so the director & script writer, Mitsuhide Fukuda & Morosawa, had to make a lot of this stuff up on the spot. And that's just the beginning of the issues Destiny faced behind the scenes. Apparently, Morosawa had beef with one of the Voice Actors on the show, so that led her to worsen their characterization in the show. As for the mess in the show itself, what can I say that hasn't been said before. So here are the cliff notes; Shinn is an annoying shit who doesn't grow as a character, the conflict feels so nonsensical & chaotic that your not rooting for either sides, a handful of characters are reduced to useless shells of themselves (both old & new), and instead of improving their new protagonist, they cave into fan demand and made their old protagonist their main one again, shafting the new one. Anything that can be said about this show, has been said. 
• IBO S2: this one has more fans & defenders, which I sorta understand. And while there wasn't much BTS drama, the creators still tried to have their cake & eat it too. Which perfectly embodies the issue of this season, it tries to make Tekkendan wrong while not making them irredeemable. Which immediately fumbles since the idea of mob story is that they make a likeable character progressively irredeemable. Even some cut concepts for the show would've served to story they were trying to tell, like Naize & even Eugene planning to betray Tekkendan. But the issue that makes this season worst is that how they handled Gjarllhorn. The new members are unlikeable pricks, and they're supposed to be the heroes we're supposed to be rooting for. But what grinds my gears the most is how they made McGillis incompetent compared to S1 and how they brought back Gallieo, just because the crew liked his VA (which is a really stupid reason to retcon his death). I can go on, but like Destiny, anything that can be said about this season has been said all ready.

Now the real question is, which one's worse: Destined to be bad or Iron makes my Blood boil O+?

For me, I guess I can look at what they offer. Like both equally has good Mecha action & great music (something a Lehman uses to justify slop). But a mark for what makes a Gundam series good, is their theme (not the opening). SEED Destiny may have pretty bad writing, but it has some themes of propaganda, information manipulation, and pre-determined Destiny. IBO S2 still had some deep themes of poverty & children being forced into brutal environments to keep bread on the table. Soooo….. Destiny is marginally better in my opinion
