How many positive and negative reviews are there?

As a first step in a sentiment analysis task, similar to other data science problems, we might want to explore the dataset in more detail.

You will work with a sample of the IMDB movies reviews. A dataset called movies has been created for you. It is a sample of the data we saw in the slides. Feel free to explore it in the IPython Shell, calling the .head() method, for example.
