Yeah action thus far is pretty neat. But I noticed the art at the begging of this episode to be sloppy (or at least I got that impression). The setting and lore are very appealing to, dunno if the train travel will get old further into the show but until now it worked nicely.
I liked the cartridge "invention"/explanation even thou the sword thing seemed silly but I was spoiled since the first OP so had it discounted and it was the only way to make mister samurai cool against those steampunk guns.
Together with Re:zero is my favourite (wich is not saying much tbh) show and one of the only 3 I follow in a more or less weekly basis.
