I rather enjoyed this mini-series chronicling the production of four classic movies and giving us some behind the scenes insight into what it took to get them made.
The films in question are "Dirty Dancing", "Home Alone", "Ghostbusters" and "Die Hard". The story behind the production of each is told using interviews with the cast and creative teams, mixing in footage from the time and excerpts from the film, and other films that make a more complete story. There's a playful narration and a number of animated gags to help make it more palatable.
To start by adding my opinion to all the others about the narrator. Would I have preferred a slightly more serious tone, yes I probably would. But did it ruin the series for me, no not at all. I'm a film fan, and I knew some of these stories before I watched the episodes but I understand that the narration and that style made it more palatable for a wider audience, and I'm OK with that. There was enough work done digging into the stories to make them worthwhile for me too.
I really like that the focus is on creative teams, producers, writers and directors rather than on the actors. Not that I don't like actors, but their stories are more gossipy-type stuff, like the section about the poor relationship between Jennifer Grey and Patrick Swayze. I prefer to hear about the other issues that stem in trying to mount a production, "Die Hard" and its helicopter problems, the financing issues, the replacement writers being brought in. Most of the major actors involved in these films aren't interviewed anyway.
If there are enough films that have worthwhile stories to tell (something other people might consider when they're bemoaning why these particular films were chosen), then I'd look forward to watching more in this series.
