No summer weekdays, movie length a little too long - reduced repeated viewers, and a lot of adult skewing competition didnt help.
However it is still 20m ahead of the 3rd film, and weekend numbers are similar. 5th weekend hold for the 3rd film is strong, which I think the 4th cant match.
Overseas its a different story though, seem to be outperforming the 3rd film everywhere I checked. I mean there's Donnie Yen in this... so huge appeal here in Asia.
