I buy/view/listen to a lot of music video's (read, sorry night life) and this one was a disappointment. Sound varies too widely act to act. Couple of goosebump moments (I love the Mega-Guitars on Kansas City) but mostly a smorgas-bored of available talent putting in their charity work. Zero additives for the video freak and no real explanation of charitable intentions ever given. Borrow this from someone instead.

Ex Output:
Negative

You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can.

Ex Output:
Negative

I'm not sure why this movie didn't do well. It has it's faults but so do many movies that others praise. My biggest complaint about this movie is it has several editing problems. Overall...It is a very entertaining action movie with a fantastic story line.

Positive
