That was a pretty good.
The part where it's cutting back and forth between the three storylines was a masterclass in tension.
My two minor gripes are that the aliens managed to ride the boat and drift all the way to the island, and the length. Felt kinda short to me and it felt unresolved, like it ended in the middle of a scene.
That said, I'm sure they intend to pick up right there again in the third one, if there is one.
Overall I enjoyed it quite a bit, but would still take the first one over this one.
Man, I missed the movies.
