Lack of good storyline.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

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

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.
