You know how some videos they allow you to listen to a Commentary while watching the movie. Sometimes they give a bit of trivia to what’s going on. I don’t care to watch it. One, I want to just watch the movie & even if it’s a movie I wouldn’t mind watching again, I don’t want to be distracted. Now, AFTER, bonus features, are different. I like watching those.
It's not something I've ever really enjoyed, I will watch the features that accompany a film, those are usually interesting, but commentary over a film annoys me.
I've seen a lot of the Harry Potter ones on the blu rays and enjoyed those as they're not only audio but also visual commentary and have interviews with the cast etc throughout the movie. It's a new way to watch the movie!
I do have trouble concentrating on most audio commentaries though.
As much as I know that is a feature when watching a movie I am someone that prefers to just watch the movie as I would normally and not bother with the commentary. I find that I get easily distracted by the commentary and it results in me missing stuff in the movie so I just leave the commentary.
