The pull request with all the code.

a lot of this method should really be extracted into a MovieFinder service object (naming could be different)... but really this `show` action should really be something like this:
``` ruby
def show
  @movie = MovieFinder.new(params[:id]).find_movie
  @rating = current_user.ratings.find_by(rottentomatoes_id: params[:id]) || current_user.ratings.new
  @friends = current_user.friends
end
```
