Every decade has its own kind of special movies and this documentary gives a very good overview. The problem is that it races through the decades and you only get a few sentences about each movie. There is no deeper exploration. Two minutes per movie and on to the next. It also feels a bit selective at times althought I could not point my fingers to what movies they left out. Then there are movies mentioned as being revolutionary and influential that I haven't even heard of.
In my case this was just a reminder of the movies I had seen and the ones I didn't, with little informational content. And that a lot of the high praised and awarded movies did little for me. Maybe it could serve as a guideline for younger movie fans as to what movies they should watch. At the same time I think everyone should explore the movie history on their own.
One other thing. The sequence in which the episodes were broadcast is wrong. I've watched the first three and the third clearly was meant to be the last which would make a lot of sense. You should start with The Golden Age, finish with The 2000s and watch the rest accordingly.
