What's Good:

Inventive plot, some sequences you might not have yet seen in a hollywood movie.

What's Bad:

Lacks on the story part -- at the end you feel like its hollow somewhere.

Verdict:

Upside Down is a experimental plot which the audience may like or otherwise.

Watch or Not:

Watch it if you're bored of conventional sci-fi movies and want something new.
