To begin, I shall admit that I am biased in my answer, but I shall try my best to be impartial.
Being addicted to video games is not a bad thing, for a multitude of reasons. To begin on the pure addiction side, it is a matter of addiction of the same type as television or books, in that it is simply an activity that one is addicted to and not a substance that could cause harm. The fact of the matter is that one can become addicted to anything, we just tend to target the more wide spread ones as a problem rather than the purposes for the addictions in the first place.
On the pointless wastes of time issue, I shall again say that it is definitely not the case. Video games are an interactive medium and, as such, can be more productive than any other medium by virtue of the fact of the actions required of the viewer (Reading a book or watching a movie causes little to no active thought on the viewer for the actions to take place, but a game requires you to actively to perform the actions in question.). The problem is that many viewers and developers tend to overlook this detail of the medium and the medium is still in it's relative infancy (Remember that people thought rock and roll was converting people to Satan as early as its conception.), but many games do touch on major issues in a mature way (The Persona series is about people's personal identities, is part of a larger game series about oder and control versus anarchy and chaos whilst teaching the actual better path lies in between; Mass Effect 2's Geth mission is about religion in the sense of eradication of forcible conversion, an issue that may sound out dated, but during a war where both sides are claiming religious reasons for fighting it is actually quite a bit more relevant then one may realize; even Pokemon's been filling their games with issues since the get go, and the most recent one being how neither side of an argument is almost ever truly right, and that one must seek an understanding of both sides in order to find the answers to life.).
The reason it gets so much attention is because we have a 24 hour news cycle, almost anyone can access the Internet whenever they want and say anything they want with a level of anonymity previously unavailable, and that we consider it an easy target due to its name (Game has childish connotations.) and the fact that it is a medium that has just been made within a recent amount of time, has developed at a rate previously unheard of (due to technology of other fields being used in it.), and not enough data has been found on its effects on human psyche.
Social skills is the only matter that holds a level of credibility, as if one acted the way they do whilst playing a game our social structure would probably crumble. But this is due to the amount of anonymity given to those who play games (If you want to see a man's true face, give him a mask. I believe that is the correct quote.) and developer's who simply didn't see certain pieces of human nature coming when making the games.
