Any chance you could share the MEN script?It's the classic thing where an artist has had forever to polish their first work while the follow-ups are made up on the fly.
Obviously Garland has been writing forever, but production and post eat into a lot of his time and it's very noticeable in his output (I disliked Annihilation and thought the script for this was serious nonsense (and he also wrote some random animated film for his wife that... Isn't as bad as those other two actually, but is the sort of thing that won't be made)).
