This mix of genres of the early cinema deserves a mention as one of the best movies in the second decade of the century. Technically, Griffith totally improves the good things made by previous directors. Acting is good, editing is crazy and the narrative structure is revolutionary. The movie offers epic war scenes just as romantic love scenes, and honestly dosen't look like a 1915 movie.
The first half is highly enjoyable, the second half is racist sometimes at unbearable levels but it's part of that old mentality. If you love cinema history, this is a must watch masterpiece.
