I just watched this movie yesterday (I have small kids. I'm perpetually two years behind on movies). I really enjoyed it!
I did snag the five figures and van when they first came out though, and you guys are right, most stores put out a case or two, they got snatched up, and that was it. Goners. Got an extra van to make a Punisher battle wagon out of it.
Makes you wonder, while sales had to have been modest due to little product actually hitting shelves, what did see daylight sold pretty well. You'd think that would have at least prompted the 2nd wave... but I guess it would have had to be in the pipeline already. Maybe some factory worker in china will sell a few other figs down the road!
