It's entirely possible that sending the audience out feeling lousy was intentional

The film creates a perfect balance between action and depth of basic needs, in the midst of an infertile atmosphere.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
