I liked episode 2. I haven't tried to look up Moon Knight's history and bio, btw, preferring to just go along for the ride for this series.

I am really tripping out on Steven Grant's perceived working-class-London-missing-consonants-and-cockney-ish-rhyming accent. This sort of dialogue you would expect from a Guy Ritchie film ("bruv", "laters gators", "innit", etc); definitely not in an MCU film, where there are, ironically, quite the number of britons donning polished american accents (e.g. Benedict Cumberbatch, Tom Holland).
Maybe this persona of his has watched too many british gangster films?

I don't think the schizo bits would have worked quite as well had the contrast in accents not been as pronounced.
