Everything about this movie is fascinating, even its numerous flaws. It is as ambitious a movie as has ever been made, and if you adjust for the era, it might also be the most lavish, expensive, and painstaking. Even today the scope and detail stand out, despite the many technical limitations in its era. Likewise, the enormous cast list contains many names that silent film fans will recognize at once, with well-known performers even in some of the minor roles. Then, you could write many pages about the stories, which are filled with weaknesses, but which are also so interesting that you never want to miss what will happen next.

The concept behind "Intolerance" is as enterprising as it gets: no fewer than four complete, independent story-lines, with the movie switching back-and-forth among them, not necessarily in consecutive order but with a definite plan in mind, all in order to get across the idea suggested by the title - that is, that intolerance of others' beliefs or lifestyles has been a destructive force throughout history. It is generally understood that there is a strong dose of defensiveness behind this plan, since the ideas promoted in Griffith's previous film had earned for him some severe and well-justified criticism. This personal motivation could well explain why "Intolerance" is often so overblown, and it also is interesting in light of the stories chosen to illustrate the main themes.

The two most straightforward stories - the persecution of the Huguenots in 16th century France, and the persecution of Jesus Christ by the religious leaders of his day - are also the most believable, and yet they do not seem to get quite the screen time or the lavish detail of the other two. The contemporary story may have been the most important to Griffith, and it is a full-scale melodrama, full of heavy-handed developments and very unlikely coincidences, yet certainly a story that will hold your attention. The Babylonian story is at once the strangest choice, the most extravagant, and the most fascinating of all. As history, it is as distorted as (or more so than) any of today's movies. Trying to pass off Belshazzar of Babylon as a model of justice and tolerance is just weird, and the entire historical scenario is at best an imaginative embellishment of the truth. But the involved story that Griffith tells in this setting is so exciting and entertaining that you just can't take your eyes away from it.

Much, much more could be said, but anyone with an interest in silent movies or in cinema history will want to watch it and draw his or her own conclusions. Whether you want to analyze the vast array of themes, events, and ideas, or whether you just want to sit back and enjoy a fascinating spectacle, the three hours fly by very quickly, and it's a movie you won't forget.

• The inspiration for this film came from D.W. Griffith's surprise at the loud protests against his previous film, The Birth of a Nation (1915). In response to those attacks, he wanted to illustrate the problem with intolerance to other people's views.
• The massive life-size set of the Great Wall of Babylon, seen in the fourth story, was placed at the corner of Sunset Boulevard and Hollywood Boulevard (in Hollywood, California) when the movie was completed. It became a notable landmark for many years during Hollywood's golden era. It actually stood on the lot of the studio on Prospect Avenue near the Sunset & Hollywood Boulevard junctions in the eastern end of the city. It was the first such exterior set ever built in Hollywood. Falling into disrepair, it was eventually torn down. Years later, this same Babylon set was replicated as the central courtyard design for the new Hollywood & Highland complex in Hollywood, which opened in 2001.
• After filming wrapped, the Los Angeles Fire Department cited the Babylonian set as a fire hazard and ordered it to be torn down. D.W. Griffith discovered that he had run out of money and was therefore unable to finance its demolition. The set stood derelict and crumbling for nearly four years until it was finally taken down in 1919. By then it had fallen apart enough for it to be dismantled at a sufficiently low cost.
