Cryptic Movies: What happened?

Christopher Nolan far exceeds the whole "wtf" moments in movie making: The Prestige, Inception, etc.

What’s the last cryptic movie you watched?
What did you think was going to happen?
How do you feel about what actually happened?

Last movie: Safety Not Guaranteed (http://www.imdb.com/title/tt1862079/)

I thought:
I thought it was going to be a mellow drama about falling in love and making new friends.

What actually happened:
They fucking did it. They time traveled.

Or, at the very least disintegrated themselves in a very elegant scifi suicide.

At no point did anyone confirm that he built a time traveling machine.
Sure, there was an investigation and they were amazed that he spent so much time drawing dribble on papers, ala A Beautiful Mind.
But no one actually knows enough science to confirm that what he was doing was legitimate.

We can conclude, based on very loose information, that they did time travel.
Or possibly just de-atomized themselves and are now dead. Forever.

Sticking with time travel, they could still possibly be dead.
As with some popular theories for time travel (as noted on Breaking Bad), the person to time travel will be destroyed entirely and a brand new, exact duplicate will be created on the receiving end of the device.
So, you’re not really travelling so much as you are just creating a clone in the past. Or future.

Speaking of cloning, isn’t there some widely believed notion that when you clone a clone (no longer having the original product), that you get deficiencies introduced with each new clone.

So, using that rule, wouldn’t time travelers who travel multiple times, sooner or later, be malformed and eventually thinned out of existence?

It would have been nice if there was a scene during the end credits where the other two journalists went to check the tin can (if they were actually given that knowledge) and find a note.

Some form of evidence that they didn’t commit suicide. ANYTHING!

All things aside, you can see how crazy he is and how validated it is given that he discovered time travel.

Cute show.
