I've never seen Samurai Jack before, but recently I've been watching it while I do other stuff around the house (mostly playing Fire Emblem). I can't remember what caused me to want to watch it after not paying attention to it for years, but something did so I am.
It's pretty great. I'm a little over twenty episodes in and I don't think there's been one yet I didn't enjoy at least some. It's interesting and funny, the animation is great, and Aku's voice is the best thing I've ever heard. I seriously want his voice actor to narrate my life and every audio book from now on. There's also a surprising amount of classic sword and sorcery beefcake, with Jack getting stripped down to his underwear through various and battling dudes all ripped and half naked and shit like every other episode. That kind of thing would come off as ridiculous with a female hero, but it's refreshing to see with a male character every once in a while.
So I'm extremely late to the party on this one, but I can see why this show is so highly regarded. I never really watched Cartoon Network as a kid so I think I probably missed some stuff. But I love Adventure Time today and there's definitely a common thread between them. And I just found out this morning that apparently there's going to be a new season on Adult Swim later this year, so there's going to be more to watch. Pretty good.
Also, that episode where he wanders around in the ruins of his old village straight up has a cameo from Ogami Itto in it, which is cool.
