I saw these films totally out of order -- EPlan3, EPlan1, then EPlan2 -- and I'm writing this while finishing EPlan2. As action films go, these have some brains because they not just muscle & punches, they're also a bit of a chess game. EP1 was bigger than reality but relatively believable. EP2 should be considered sci-fi, and for the series IMO went too far (good to see the actor from The Expanse though). EP3 got back to it's roots and is similar to EP1 ... but is more reality than 'bigger than reality'. So far as I can tell, watch EP1 and EP 3 but you can skip EP2 -- it's too far different from EP1 and it didn't seem to have sway on EP3.
