I've been meaning to watch Gurren Lagann for a while. I've also been thinking of trying to get into some mecha series, so I guess I'll get around to that sooner rather than later.
I actually don't have too big of a backlog right now, but I've been spending all of my time working on my video game backlog, ha ha... Case in point, I've been about halfway through the second season of the Monogatari series for months now. Both parts of Nekomonogatari were great, Kabukimonogatari was kinda eh (nowhere near enough Hachikuji), and Otorimonogatari was really good. At first it kind of seemed like they were rehashing parts of Hanekawa's arc with Nadeko, but then it went in a completely different direction in a way that surprised me. I'm actually kind of happy about how it played out, because before this she had easily the least development out of all the girls. Ideally I can get mostly caught up before the new season starts.
Beyond that, I've really enjoyed the last few chapters of JoJolion. I do kind of miss the earlier days back when everything was enjoyably cryptic and every weird reveal just led to even further questions that just kept you guessing, but it is nice that we now have a much more clear path towards how this is going to wrap up. My money is on Kaato as the main villain... her or some higher ranking Rock Human we haven't met yet. I already really like the plant appraiser, very few characters can make such a good first impression. I am kind of upset that we're dealing with everyone running away from a long-range remote stand again, though. It was kind of refreshing at first, but now almost every fight is like that.
Berserk is also on a consistent schedule and the recent chapters have been fantastic, and Hunter x Hunter is apparently coming back next month. Nice.
