That's Spider-Man, though. Spidey always sells no matter what. That said, no, I wouldn't classify this as any kind of home video hit. It's not a bomb - I mean it still did better than other modest performers of last year like RoboCop, Riddick, Hercules and Anchorman 2, but it's still well below most of the year's major blockbusters.
It honestly deserved more than what it made. Did it even break even with the domestic BO?
Just give Emily's character her own movie, honestly.
It's a wonderful self contained story. It doesn't NEED a sequel!
