1. Load in the movie dataset and set the index as the title:

>>> movie = pd.read_csv('data/movie.csv', index_col='movie_title')

2. Create a variable to hold each set of criteria independently as a boolean Series:

>>> criteria1 = movie.imdb_score > 8
>>> criteria2 = movie.content_rating == 'PG-13'
>>> criteria3 = ((movie.title_year < 2000) | 
                 (movie.title_year > 2009))

>>> criteria2.head()     # all criteria Series look similar
movie_title
Avatar                                         True
Pirates of the Caribbean: At World's End       True
Spectre                                        True
The Dark Knight Rises                          True
Star Wars: Episode VII - The Force Awakens    False
Name: content_rating, dtype: bool

3. Combine all the criteria together into a single boolean Series:

>>> criteria_final = criteria1 & criteria2 & criteria3
>>> criteria_final.head()
movie_title
Avatar                                        False
Pirates of the Caribbean: At World's End      False
Spectre                                       False
The Dark Knight Rises                          True
Star Wars: Episode VII - The Force Awakens    False
dtype: bool
