Not necessarily. I don't often go to movies but I do buy them. I just bought "Memoirs of a Geisha" which is a Spielburg film and have watched it three times. I have the 2 disc version. The values expressed in the film are good ones and it is entertaining.
The commentary on the second disc is simply wonderful showing how the set was built and various shots were done, some with mind boggling technology. You know, the technology that American film makers are known world wide for ... the stuff we see but don't notice because we are so enchanted with the film.
American movies can make dreams come true ... not many countrie's films even attempt the feats that we do. American innovation at its best.
And I bought all 4 seasons of 24. I got hooked and watched them one after one at home ... actually while I was playing online. Kiefer Sutherland is terrific as Agent Jack Bauer saving the US and on call for the President.
If you get them be sure and watch the extras ... more of that American moviemaking know how!
