Like:
The lab setting (very cool scenes could be done here)
The idea of a "survivor" being debriefed after an encounter (finally)
Humans studying the Predator. Finding out things as they/we go vs. being told the "lore" ala homeworlds, the "story" scene in AVP, Basically the entire Predators movie. "Studying" the Pred still leaves the mystery intact with a slow leak of new lore. Much better way to do it. Should have been this the entire time.
Overall it's a good premise. (Whether or not the story told is good-within the premise, is unknown)
Holbrook looks like a possible bad-azz
Don't like:
The Pred(s) shown look like AVP and Predators knockoffs are they just plain used the suits. Not a fan of literally any of the suite designs after Pred 1, 2 and the AVP2 pred. Needs to be kept simple. These superhero suit-looking things are just dumb, along with the "big-headed" Ice age looking masks. just Dumb. Keep the sleek, creepy-bug-like design and tweak that.
Kid activating the ship, flying, crash landing. Dumb, tacky, easy way out sorta thing. Lazy writing there.
