I honestly don't have much of a problem with the Scully thing. You're allowed to have your opinions of course. You may think Lennon was a douche and that's fine, but the shit Sam was saying about him was factually wrong and utterly ridiculous. So when you liked that post, it reflected negatively on you in my eyes.
Yeah, I love Gintama. Its slapstick humor is so over-the-top ridiculous I couldn't help but burst out laughing so many times. The ridiculous ways it subverts the audience's expectations is genius, not to mention the many times it gets away with making fun of other anime, especially shounen anime like Naruto and Dragon Ball. I find it hard to stick around for entire seasons for comedy series, but Gintama's jokes land so well that it easily became one of my favorite anime of all time.
I haven't watched the final season yet. I just never got around to it. But damn, I want to someday. lol
