I acknowledge that Adventure Time is a very well put together show; it's that rare instance of a show where the more you see it, the more you start to notice that there's a clear path that the creators were setting up for the show and are slowly unraveling it. However, there's something about it that's a bit alienating to me on an aesthetic level. Maybe it's the art style or the character designs; I can't really put my finger on it but it's a bit of a put-off.
Chris' take on Regular Show is probably the best I've heard. There's something about how the show takes very real-life situations, especially for young adults, and anxieties and puts it's own weird spin on it that I've always found enjoyable. It's pretty interesting how despite whatever crazy thing the show throws at you, in the end, the show treats it like it's just all part of a, for a lack of a better word, regular life. It's also a show that I didn't expect to surprise me with some of the arcs the characters get to go through, such as Mordecai learning to let go of Margharet.
Still, I think my favorite show on CN right now has to be Steven Universe. It's just getting started, but it's already building up a lot of steam. Over the last few years, I've seen cartoons that are trying to push for a more optimistic look on life, featuring characters that just want to be happy and bring people together. The character of Steven is a very good example of this. He's defined by his drive to be friendly and his kindness, as his prime role in the series so far is to teach The Crystal Gems to basically be a little more human. He does screw up a lot, but it's all part of him growing up. Plus, it should go without saying, but I like that at no point (so far) his weight is either a problem or a source of cheap laughs at his expense. All in all, I hope he can be seen as a good role model for young boys, much like Finn from AT.
It's also worth pointing out that the majority of the supporting cast of this show is female, and all of them are distinct in personality, interactions with Steven, and even physique. I really dig that.
So yeah, if you haven't seen Steven Universe, fix that.
