I guess, you mean the teaser, because the final trailer was good. The teaser wasn't bad either, just the effects were still a little rough at that point.
You can't just take the OS numbers without context. The original Spiderman did about the same OS than DOM, Superman did more OS than DOM. If Superman has never blown up OS it also has never blown up DOM. Batman indeed had historically a somewhat weaker DOM:OS ratio.
Reboot does matter OS just as much as DOM, the difference is that the growing OS market is concealing the fact that attendance goes down in developed markets.Pirates 4 is not a reboot in any shape or form, it's featuring the same actors, most of all Depp.
To be fair, TDK didn't have China, SM3 did (i know, it didn't gross a lot but still). And TASM is a reboot while TDKR is not. Just because some people ignored the reboot factor, doesn't mean its performance is bad in any shape or form.
