So maybe I shouldn’t have retired from box office predicting, after all — my Iron Man 2 prediction proved right in the ballpark. Its estimated domestic haul was $133 million, so I was off by just $6 million.There were a lot of people who were predicting much bigger things, though. I notice a few were thinking this movie was going to threaten The Dark Knight’s opening weekend records, or at least beat Spider-Man 3. As a result, people are playing up the fact that there were no records set. The big headline everywhere is “No Records for Iron Man 2″, overlooking the fact that a $133 million haul is a mighty good performance that most movies would kill for. Like I said before, though, I think people are starting to tire of the superhero/fanboy genre at the movies, and I think that’s one reason why this movie didn’t set records. There have been just too many of these types…
