Truly a work of art. I don't care if it is live action, I count this as a quality comedy sketch with production value. Really though, very fun with both your deliveries. Like @NekoMika said, very reminiscent of old YouTube sketches and I think the reason for that is that it conveys the dorky buddy atmosphere very well, with stuff like the ringtones and the dumb "Gonna check my mail" song. Henry's face really was just fantastic, I cannot get enough of this man. I would watch a 5-minute short that's just a single shot of Henry making faces. He really old it all perfectly, and, my God, that epic guitar playing. Littlbox was more subdued cause he is supposed to be the same one, but it was nice and he still had plenty of charm. I feel like the sandwich exchange wasn't quite as interesting as the rest, though, just felt pretty standard, littlbox's acting during it wasn't really as good as in the rest of the movie. The end really brought it back, though, really saved it so hard.
Overall I really like what you guys did here, great vibe, funny jokes, wholesome and despite being live-action, I think it does justice to the NG community.
