The movie follows the style of several stories interwoven throughout the plot, same as many successful ones before it i.e. Babel, Crash and that is just at the top of my head..

That being said, here we go..

The movie follows a very cold and truthful view about what people are willing to do to get what they think or believe are their dreams. It is not about that dream per say but about what you have to do to achieve it.. might it be to leave a loved one behind, give up on your hopes, sell yourself to the highest bidder or plain out hurt yourself..
What I liked about it, is how it shows you that after all the dust settles in you would discover that you might have gotten what you thought you wanted but you have lost something far more precious which is yourself and what is left is just not enough..
That the American Dream might not be the fairy tale that everyone is selling it out to be after all!!!

Of course since I liked the movie.. It is safe to say that the critics didn't..

The film received negative reviews.

On Rotten Tomatoes the movie received 16%, of 106 critics gave the film a positive review, for an average rating of 4.1/10.
The site's consensus reads that: "Crossing Over is flagrant and heavy-handed about a situation that deserves more deliberate treatment, and joins its characters with coincidences that strain believability."

Metacritic, which assigns a weighted average score out of 100 to reviews from mainstream critics, gives the film a score of 38 based on reviews from 31 critics indicating "generally unfavourable reviews".

However, I invite you to check it out.. It is worth the watch..
