I am a fan of the Big bang theory and they seem to mention this in several episodes. I have never watched a movie with directors commentary, have u ?
If yes do tell which movie was it and was it worth watching with the additional chit chat.
I have done it for various movies a couple of times. Sometimes it's pretty droll but other times it will be a funny cast member and the director which helps. Then it's like friends talking about a movie they've watched.
A few times. Can be pretty damn interesting and funny at times, but can also be super boring and annoying. I've also listened to the commentary for every single episode of Futurama, the only series I've done that for.
And then I've also listened to the commentary in a few games like Half Life and Tomb Raider.
I can't say that I have done so with movies, but I have replay adventure games and some other indie titles with developers commentary.
It provides you with better insight into why they have opted to do this or that, how they were inspired and so on. Generally it are 'artists' commentary and I like it, especially when it is made by someone like Tim Schafer.
