Nobody is saying you need pot to appreciate the show. But do you need popcorn when you're at the movies? No. But is it awesome to eat popcorn at the theater? Yes. So why the fuck not? Same with weed.
Anyhow, just watched the episode. So is this show going to keep being a slice of life drama? I'm getting sick of subplots. The different settings are somewhat interesting, but this episode was just kind of a pleasant waste of time. I liked it better than the 3rd episode anyway, because it was a bit more of an actual story.
I'm suprised he hasn't switched to a new body, but at least we've seen something that I assume is what he used to look like.
