Art and originality aren't perverted or dead, it's just the influx and amount of information via the Internet that makes one feel that way. (Potential) Artists and art lovers weren't exposed to the works of millions of people before the Internet, but today, everyone has their personal webspace and it's easy to lose track and hope for "art" until you realize that those kinds of people always existed. They were just anonymous and far away from you so you didn't know.

EDIT: Also, saying since art is tacked onto worthless stuff, games can be called art doesn't really mean much. I don't think any good art was appreciated during its own time alone. I am always reminded of Don Quixote, which is often regarded as one of the best written works ever. It was originally "just a parody" of popular knight novels during Cervantes's time. Fast forward till today, and nobody remembers the knight novels, but everyone looks at Don Quixote as a work of art.
What I'm getting at is that whether someone calls Heavy Rain, Bulletstorm or Crash Bandicoot art matters very little, because as time goes by, people might be less enthusiastic about these titles and be more objective about it since they weren't exposed to the actual release. We will probably end up with only a few games being remembered. I'm not talking about nostalgia though, like the way people feel towards Mega Drive Sonic games, but rather something in like 50 years. And I'm guessing a good deal of those games will be stuff that was panned or received lukewarm response from reviewers (here's to hoping Nier and God Hand get up there ).
Remember that movies were entertainment only when they first appeared, being 5 second clips. Gaming still needs to evolve much more as a creative medium, but it did manage to evolve into an industry, which is slowing down that process, in my opinion. What the Heavy Rain author said (in some thread, either this one or a different one, not sure) about games needing to mature and change was kinda true, but I disagreed with him because I though he went the completely wrong way about it and was on an ego trip.
