Code Review

Do not merge this. 

This branch is for comments, only.
Typically, if a line is longer than 80 characters, I continue it on the next line, and indent once.

Also, this would be a great opportunity to push some of the complexity of this statement to the Movie class. 

```
def paginate_search(query, page = 1, results_per_page = 20, order = :title)
  order(order).where("title ILIKE ?", query).limit(results_per_page).offset((page - 1) * results_per_page)
end
```
