I saw Avatar last week.
Now, I know this is horrible, but I went into the film not realizing it was a 3D film. (Okay, you can stop laughing. No, really. Stop laughing! It's not like I follow this sort of stuff!)
And, of course, this is the only 3D film I've ever seen.
Had I realized it was a 3D thing, I'd have probably not gone. And it would have been a major mistake.
While the movie was somewhat predictable, it *WAS* entertaining. And while I'm not one who is impressed by special effects, I was impressed by the 3D. I felt that it made the movie "larger," and therefore, better. In fact, I think the movie would have been considerably less enjoyable if it WASN'T 3D.
All in all, the movie gets the typical, "It was okay," rating from me - meaning that I wouldn't object to seeing it again, but won't be gathering friends up because they absolutely *MUST* see it.
HOWEVER, the movie, along with a news story I read recently, may have had an unexpected impact: I may put off for a while longer the purchase of an HD TV. The story I read questioned whether 3D would be next, and which TVs might (or might not) support it. To me, that sounds like a reasonably compelling argument not to spend money on a major purchase just for the opportunity to spend more on every DirecTV bill at this point.
