Story hooks vs. Explanations

"Hey, did you see what I did there?"

 I've just seen both Pacific Rim and The Wolverine. Both are popcorn movies and not meant to be particularly deep. Both had obvious and less obvious elements included in their construction. Some of those included details may have been meant to support other parts that ended up on the cutting room floor, but I'd like to think that sometimes an artist/writer/director/actor includes some detail on the sly because the story-word demands it, even if very few people will notice what they've done.

 I also think that including open hooks instead of set explanations makes for richer writing and better stories. People think more when you don't do all of their thinking for them or demand that their "take" is the same as you, the creator, intended.

 I don't intend to "spoil" either of the movies, but if you're worried about it you'd probably better not read the rest.
